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.

Answer . Distilled water is homogenous not heterogenous.
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.…
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 h…ydronium ions, because (like many other solvents) water reacts with itself: 2 H 2 O() H 3 O + (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 -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.
it is a compound
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.
cos it has no solutes in it
Mineral contain is very less

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 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.
