Fires involving ammonium hydroxide may be extinguished with dry chemical, CO2, Halon, water spray, fog, or standard foam. Ammonium hydroxide may be shipped via air, rail, road, and water, in containers bearing warning labels that differ depending upon the density, specific gravity, and percent composition of the solution being shipped. Consult the regulatory requirements of the US Department of Transportation before shipping.

The United States Pharmacopeia (USP) is engaged in the ongoing challenge of obtaining the information needed to create and sustain up-to-date quality drug product monographs for FDA approved drugs, including OTC drugs. The USP also embarked on a global initiative to modernize many of the existing monographs across all compendia.
With silver nitrate TS, solutions of chlorides yield a white, curdy precipitate that is insoluble in nitric acid but is soluble in a slight excess of 6 N ammonium hydroxide. •B. When testing amine (including alkaloidal) hydrochlorides that do not respond to the above test, add 1 drop of diluted nitric acid and 0.5 mL of silver nitrate TS to a ...

Assay— Transfer about 2.5 g of Ammonium Sulfate, accurately weighed, into a 500-mL conical flask, and dissolve in 50 mL of water. Add 50.0 mL of 1 N sodium hydroxide VS, place a filter funnel loosely in the neck of the flask, and boil until ammonia is expelled (about 10 to 15 minutes) as determined with litmus paper.

Limit of alkalies and alkaline earths— Completely precipitate the aluminum from a boiling solution of 1 g of it in 100 mL of water by the addition of sufficient 6 N ammonium hydroxide to render the solution distinctly alkaline to methyl red TS, and filter. Evaporate the filtrate to dryness, and ignite: the weight of the residue does not ...
Centrifuge and wash the preci- pitate with three 1-mL portions of water, and discard the washings. Carry out this operation rapidly in subdued light, disregarding the fact that the supernatant solution may not become perfectly clear. Suspend the precipitate in 2 mL of water and add 1.5 mL of 10 N ammonium hydroxide.
Procedure— To the Test solution add 25.0 mL of Edetate disodium titrant, and adjust with 2.5 N ammonium hydroxide or 1 N acetic acid to a pH of 4.7 ± 0.1. Add 20 mL of acetic acid-ammonium acetate buffer TS, 50 mL of alcohol, and 5 mL of dithizone TS. The pH of this solution should be 4.7 ± 0.1.

Aluminum— With 6 N ammonium hydroxide, solutions of aluminum salts yield a gelatinous, white precipitate that is insoluble in an excess of 6 N ammonium hydroxide. 1 N sodium hydroxide or sodium sulfide TS produces the same precipitate, which dissolves in an excess of either of these reagents.
Hold the pipet just above the surface of the 1 N sulfuric acid VS in the conical flask, and transfer about 2 mL of the Solution into the flask. Insert the stopper, mix, and again weigh to obtain the weight of the specimen. Titrate the excess acid with 1 N sodium hydroxide VS, using methyl red TS as the indicator.
