Arsenic acid, disodium salt Specification

Arsenic acid, disodium salt (CAS NO.7778-43-0) is high toxic. It is incombustible material. Arsenic acid, disodium salt (CAS NO.7778-43-0) will release toxic arsenide vapor by heat. So the storage environment should be ventilate, low-temperature and dry. Keep separate from alkali, acid, food additives.
