| | POTASSIUM ARSENATE Usage And Synthesis |
| 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. |
