Usage

Reactivity Profile

A powerful reducing agent. Reacts with bases and oxidizing agents.

Air & Water Reactions

Hygroscopic. Sensitive to prolonged exposure to air. Water soluble. Reacts slowly with water.

Purification Methods

Crystallise the salt from aqueous75% ethanol or boiling methanol, and dry it under vacuum over CaSO4 or P2O5. It has also been dissolved in a minimum of water and saturated with HCl; after three such crystallisations, it is dried under a vacuum over CaCl2 and NaOH. Its solubility at 20o is 85% in H2O, 6% in EtOH and 12% in MeOH. [Hurd Inorg Synth I 87 1939, Semon in Org Synth Coll Vol I 318 1941.]

Fire Hazard

Flash point data for Hydroxylamine hydrochloride are not available; however, Hydroxylamine hydrochloride is probably combustible.

General Description
