Why use distilled water for methadone stock solution?
Answer Distilled water is homogenous not heterogenous.
Analysts use pure water so they know exactly what is in the solution. These days they are more likely to use water purified by deionization.
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
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.
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 hyd…ronium ions, because (like many other solvents) water reacts with itself: 2 H2O() H3O+(aq) + OH-(aq) At room temperature, 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 10-7M H3O+ and 10-7M 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 H2O() + CO2(g) H2CO3(aq) H2CO3(aq) + H2O() H3O+(aq) + HCO3-(aq) HCO3-(aq) + H2O() H3O+(aq) + CO32-(aq) which brings the pH of distilled water in an open-air container down to about 5.8.
it is a compound
Distilled water could be used in place of saline solution to upset a patient's homeostasis by having them ingest a fair amount of it. The human body has fluids that are sl…ightly salty and have a pH of around 7.4. Distilled water should have a pH of 7.
Distilled water is recommended to be boiled and cooled before preparing NaOH solutions to eliminate the dissolved CO2 in the distilled water.
cos it has no solutes in it
Mineral contain is very less
30 days refrigerated
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.
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" subst…ances(contaminates) in tap water the solution you are preparing has the possibility of reacting with the contaminates producing 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.
Real classified and standardised solutions should not contain impurities from undistilled water.
Tap water often contains certain ions, which could react with whatever 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.
