Sodium arsenite is a white powder solid, easy to dissolve in water, and the solution is weak alkaline. Carbon dioxide is absorbed in the air to produce sodium arsenite. Sodium arsenite is highly toxic

Sodium arsenite is highly toxic, and LD50 is about 41mg/kg. The mice were intraperitoneally injected with about 1.17mg/kg.

It is used as a common analytical reagent, insecticide and preservative, and is also used for trace analysis of iodine (arsenic method has been rarely used).
