Chemical Properties
Potassium arsenate is a colorless to white crystalline solid.
Chemical Properties
Colorless crystals.
Soluble in water; insoluble in alcohol.
Uses
In the textile, tanning, and paper industries. In insecticidal formulations (especially fly paper).
Preparation
Monopotassium arsenate(V) is prepared by calcining a mixture of equal parts of arsenic oxide and potassium nitrate in cast-iron cylinders, leach ing the melt with water, and concentrating the solution with arsenic acid. It forms white crystal crusts.
Hazard
Toxic by ingestion and inhalation, strong
irritant.
Safety Profile
Confirmed human
carcinogen. Mutation data reported. When
heated to decomposition it emits toxic
fumes of arsenic. See also ARSENIC
COMPOUNDS.
Potential Exposure
Potassium arsenate is used in the textile, tanning, preserving hides; in the textile printing and paper industries; and as an insecticide in fly baits, especially for fly paper; as laboratory reagent.
Shipping
UN1677 Potassium arsenate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
A weak base. Reacts with strong oxidizers, bromine azide, acids and decomposes on contact with strong acids producing acetic acid fumes. Arsine, a very deadly gas, can be released in the presence of acid, acid mists, or hydrogen gas.
