Why use distilled water for methadone stock solution?
Because it is a pharmacological medication, FDA regulation calls for distilled water just like any other liquid medication a pharmacy would mix behind the counter.

Solution . Distilled water is typically used in batteries (Automotive/Telecommunictions etc.) due to it's lack of mineral content and general purity. Using tap water in wet cells can create problems in the long term as minerals can form on the cell plates and affect the efficiency of the producti…on of electricity. In addition, soft water is generally not accepted as a substitute, because of the salt content from the process. (Same problem...deposits on the plates) Using distilled water increases the life of the wet cell....stick to distilled water as a first choice!...Cheers! (MORE)
Analysts use pure water so they know exactly what is in thesolution. These days they are more likely to use water purified bydeionization.
Analyst use distilled water to pretty much sterilize everything.They don't use tap water because it has impurities in it and couldcause contamination when doing an experiment.
distilled water is used in chemical experiments because you already have a control group (whatever type of water you used) and you need other groups that dont have the same water in them to compare the control group to!.
Explain how the use of distilled water in place of this saline solution would be expected to upset the patient's homeostasis?
The saline solution used in hospital I.V.s is a solution with aboutthe same water concentration as the human body. If distilled waterwere used instead, the imbalance of concentrations of salt betweenthe water and the body would cause cells to react, and the processof osmosis to cause them to bloat u…p with water, potentiallydamaging them.

Put 0.9g of Nacl in a beaker and add distilled water to make up to 100ml. that is 0.9% Nacl (Normal saline Solution). From Tade Olubunmi Ademola
Controls must be of identical composition in order to avoid affecting the outcome of an experiment. Tap water, demineralized water, rain water, lake water, etc., all have different compositions depending on the environmental conditions where they originate. Distilled water is universally the same no… matter where it is made, so long as the container is sterile. (MORE)
Water is hypotonic compared to the serum/blood. Putting a hypotonic solution in there will cause dilution and may draw solutes out from the cells to compensate. This can kill a person. Even a small amount of water must be rendered isotonic prior to IV use.
Steam irons is common since it has already been boiled to remove mineral deposits. Distilled water is ideal for topping up lead acid car batteries too.
Yes, this is one of the many dirty little secrets of chemistry: There isn't any such thing as pure liquid water . Distilled water is a very dilute solution of hydroxide and hydronium ions, because (like many other solvents) water reacts with itself: 2 H 2 O() H 3 O + (aq) + OH - (aq) At room temp…erature, about 1 in every 10 000 000 water molecules has dissociated by donating a hydrogen atom to another water. Distilled water under these conditions is actually 10 -7 M H 3 O + and 10 -7 M OH - . Hydroxide ion is the caustic component of lye, and hydronium ion makes acid solutions corrosive. However, the concentrations in water are extremely low and not at all dangerous. (For an opposing opinion about the toxicity of water, click here.) Distilled water also reacts with atmospheric carbon dioxide according to H 2 O() + CO 2 (g) H 2 CO 3 (aq) H 2 CO 3 (aq) + H 2 O() H 3 O + (aq) + HCO 3 - (aq) HCO 3 - (aq) + H 2 O() H 3 O + (aq) + CO 3 2- (aq) which brings the pH of distilled water in an open-air container down to about 5.8.

we don't use distilled water for drinking because it would be too expensive to distill all of it and in any case there are many useful minerals in the water that benefit the body. Most of the things in normal drinking water benefit us we just have to be careful that we donut have harmful bacteria or… other organisms in it. (MORE)
it can be used as a drink it is not harmful and can be used with baby formulas also it can be used in fish tanks. distilled water is fancy for "purified" water.
Distilled water could be used in place of saline solution to upseta patient's homeostasis by having them ingest a fair amount of it.The human body has fluids that are slightly salty and have a pH ofaround 7.4. Distilled water should have a pH of 7.

Distilled water is recommended to be boiled and cooled beforepreparing NaOH solutions to eliminate the dissolved CO2 in thedistilled water.
Production of pure chemicals and medicines. Any place where the contaminants in water are intolerable.. Deionized water is usually good enough for a radiation shield...
The goldfish need dissolved Oxygen in water, without it they will die. So, the answer to your question is No, Distilled water is not good for Goldfish.
Certain chemical reactions require use of distilled water. Engines in our cars need distilled water. It is good practice to use distilled water for drinking purposes.
\nPurity.

Water bath is used for uniform and steady heat transferring by heating water in it. If distilled water is not used during heating process all the salts present in normal water will settle down on the surface causing scaling and decreasing heat transfer. Distill water is free from salts and compoun…d which form scale like calcium carbonate etc. Water-bath with distilled water will work with efficiency and low maintenance. (MORE)
If an unknown solid substance is non polar will it matter if distilled or tap water is used to prepare a solution of this substance?
If the substance is nonpolar it will not dissolve in either distilled or tap water. It will not make a solution with water. You will have to use a nonpolar solvent.
Yes. Most water can be used to cure dehydration, provided it is not contaminated or salty like seawater.
How do I produce a 4 percent citric acid solution using 50 percent citric acid powder and distilled water?
50% citric acid powder = 50 g citric acid/100 g 4% citric acid solution = 4 g citric acid/100 ml distilled water Determining how much citric acid powder to use is based upon how much citric acid solution you wish to make. To make 100 ml of solution, you should use 8 g of powder.
Not a good idea to, water in nature are rarely purely distilled, it contains salts, buffers and nutrients, etc. that the fish rely on. Plus, it would alter the pH, salinity, GH, etc.i If it is in a saltwater tank, it is a must. The optimum water would be reverse osmosis water. Distilled and RO wa…ter do not contain any phosphates, nitrites, nitrates, or any other bad things. (MORE)
Yes, you should used distilled water in the battery and in the cooling system. Reason being is that distilled water contains no impurities and no metals.
By solute I hope you mean more substance...If that's what you mean then definitely the egg. Distilled water has been filtered to remove as much solute as possible.
Distillation is a process of heating some fluid and collecting the vapor, in order to leave impurities behind in the original fluid. Distilled water is a very pure form of water, with nothing added or dissolved in it. Most people don't really need to use distilled water, but for some types of …chemical processes, the added purity is helpful. Around the house, there are appliances that can work better and last longer, if they're operated with distilled water instead of tap water. These are all of the things that you fill with cold water, and the appliance heats the water before you take the water out. For example: . teakettle . bedroom vaporizer . coffee percolator . electric steam iron Some water always evaporates from inside these appliances, and when it does, it leaves behind any minerals that were dissolved in it. Over a period of time, the minerals build up to create that chalky white coating on the inside of the pot, and they can even clog the outlets of the percolator or steam iron. Using distilled water avoids this inconvenience, since the water has no minerals dissolved in it. (MORE)
How does the use of distilled water in place of saline solution in the human body upset the bodies homeostasis?
The cells of the body draw nutrients from the blood stream by way of static pressure. The general way this works is that a substance naturally moves through a semi-permeable membrane from an area of higher concentration to and area of lower concentration. Normally, a cell uses sugar by breaking it d…own into other molecules (like CO2). As the sugar is used up, and CO2 is accumulated, there is a 'static overpressure' built up between the inside of the cell and the body's blood stream, which carries the nutrients to the cell. The blood has a higher concentration of sugar and 'pushes' the sugar into the cell which has a lower amount of sugar in it. Likewise, there is more CO2 in the cell than in the bloodstream, and it is 'pushed' into the veins to be carried to the lungs. Normal saline solution matches the bloodstream's nutrient concentration, keeping the static pressure balanced. If distilled water was used in an IV, the concentration of nutrients in the blood would drop dramatically and the body's cells would 'push' their nutrients into the blood to balance it again. The cells now have no way to make energy, and basically starve themselves. (MORE)
because distilled water does not contains impurities,thus the reading of the measurement will not be affected...:)
Hypotonic solution. Hypo means "deficient". Distilled water has adeficient tone (frequency) and a neutral pH, but being devoid ofdissolved solutes it has no osmotic pressure.
pH value of distilled water would be 5,6 and 7 as interaction withthe atmosphere allows carbon dioxide to dissolve into it, formingcarbonic acid. salt on its own has no ph value but , when mixed in water the phvalue of common salt is 7 and it is neutral.
You can boil the solution and collect and condense the water vapor until all of the water is gone. That will leave you with the solid copper sulphate. You will have to let the copper sulphate dry to remove all of the water.
Distilled water is evaporated and then condensed, so it has absolutely no contaminates. Unwanted compounds in medicine could be very dangerous.
Distilled water is used because it has a pH of 7 (Acid = Alkali) Where as non distilled water can a have a pH of between 5 and 9.
Not a lot. But distillation is used to separate the components of a mixture. A scenario where distillation of urine for example is useful is if you are stranded in a desert. You can find a way to distill your urine so that the water in it evaporates and condenses so that you have pure drinkable wate…r... Distillation of ink however is not very useful unless you wanted to identify different parts of ink (MORE)
Indefinitely. It simply water that has been heated to boiling point, the steam drawn off, and condensed back into water. Distilling removes things like trace elements (chlorine etc) that are normally present in ordinary tap-water.
Just plain old distilled water? You'll get dilute Benedict's. Benedict's looks for sugar, and if there isn't any it won't react.
Electrolyte is 35% Sulfuric acid and 65% distilled water. You can add distilled water to a battery that is low, but distilled water alone cannot be used as an electrolyte.
How could you use universal indicator paper as a way of distinguishing between distilled water and sodium hydroxide solution and ethanoic acid solution?
Yes. Distilled water is neutral so would turn the paper green. Sodium hydroxide is an alkali so would turn the paper blue/purple. Ethanoic acid is an acid so would turn the paper red/orange.
Tap water can contain impurities such as minerals, and other substances though usually harmless for human consumption in most developed countries. Because of the "extra" substances(contaminates) in tap water the solution you are preparing has the possibility of reacting with the contaminates produci…ng different results than intended. Distilled water has been more or less "purified" of the contaminants so that you are fully aware of what is in your solution and can work with one less worry of your solution being contaminated.

1) Doesn't contain anything which may interfere with the experiment 2) Is much better at dissolving things than tap water
distilled water is used (as opposed to tap water) as it does not contain ions or impurities that may affect the results of the titration, usually by reacting with the acid/alkali themselves or by changing the pH of the solution.. As water is pH 7, it is neutral and will not change the pH..
Distilled water is used as electrolyte, topping off lead acid batteries for example or any application where purified water is required
It is important that distilled water is used in medicines.Otherwise, tap water, rain water, etc, will contain chemicals(chlorine, sulphur, dust, etc,) that may alter a medicine and causethe medicine to be ineffective or dangerous.

Tap water often contains certain ions, which could react withwhatever solute you use in your solution to form precipitates,which in turn would contaminate your solution.
There is no solute or solvent as distilled water is not a solution,it is pure water.
