Arsenic acid, disodium salt, hepta hydrate Specification

Arsenic acid, disodium salt, hepta hydrate (CAS NO.10048-95-0) is a kind of odorless white crystals. It will becomes anhydrous at 212 °F. The aqueous solution is alkaline to litmus. It is incompatible with strong reducing agents, strong oxidizing agents and strong acids. It is also incompatible with iron, aluminium and zinc in the presence of water. Literature sources indicate that Arsenic acid, disodium salt, hepta hydrate (CAS NO.10048-95-0) is nonflammable. Arsenic acid, disodium salt, hepta hydrate (CAS NO.10048-95-0) is high toxic. It is flammable. It will produce toxic fumes when buring. So the storage environment should be ventilate, low-temperature and dry. Keep it separate from raw materials of food. It may be fatal if swallowed or inhaled.
