CAS 1336-21-6

Ammonium hydroxide

Description:

Ammonium hydroxide, with the CAS number 1336-21-6, is a colorless, aqueous solution of ammonia in water. It is commonly referred to as ammonia water or ammonium hydroxide solution. This substance exhibits a strong alkaline nature, with a pH typically above 11, making it effective in neutralizing acids. Ammonium hydroxide is highly soluble in water and has a characteristic pungent odor due to the presence of ammonia. It is used in various applications, including cleaning agents, fertilizers, and as a pH regulator in various industrial processes. The compound can be corrosive, particularly to skin and eyes, and should be handled with care. In terms of chemical behavior, it can react with acids to form ammonium salts and can also participate in complexation reactions with metal ions. Its volatility means that it can release ammonia gas when exposed to air, especially at elevated temperatures. Overall, ammonium hydroxide is a versatile chemical with significant industrial and laboratory applications.

Ammonium hydroxide - 28% NH3 in H2O

Controlled Product

CAS: 1336-21-6

Ammonium hydroxide is a chemical compound that is used to remove sodium salts from water in the treatment of wastewater. Ammonium hydroxide is also an analytical reagent for the determination of ammonium ions by titration, and is used as a polymerization catalyst. It can be used to produce glycol ethers, which are solvents with low toxicity and high boiling points. The reaction mechanism involves the conversion of hydrogen fluoride (HF) to hydrofluoric acid (HF), which reacts with ammonia to form ammonium fluoride (NH4F). This reaction produces heat and gives off water vapor. Ammonium hydroxide is a weak base, so it will react with any strong acid, such as hydrochloric acid or sulfuric acid, but not with weak acids such as acetic acid or phosphoric acid.
