Aqua Destillata, B.P. Distilled Water.

Other tomes: King's

H2O = 18.016.

Distilled water is obtained by distilling good spring or tap water, the first portions of the distillate being rejected if a deep yellow tint is obtained with Nessler's reagent. It is also official in the U.S.P. It is a colourless, tasteless, and odourless liquid. It is stated in the B.P. that the water should contain not more than 0.005 part of ammonia per million, but that standard is unnecessarily severe for dispensing purposes. For physiological purposes, as in making Ringer's solution, it is necessary that the water should be slowly distilled in glass vessels.


The British Pharmaceutical Codex, 1911, was published by direction of the Council of the Pharmaceutical Society of Great Britain.
