arsenic acid, sodium salt is a colorless to white crystalline solid. arsenic acid, sodium salt is soluble in water. arsenic acid, sodium salt is toxic by ingestion.

Soluble in water forming weakly acidic solutions.

Acidic salts, such as arsenic acid, sodium salt , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

(Non-Specific -- Arsenic) High mortality rate due to acute poisoning usually within 48 hours.

When heated to decomposition, arsenic acid, sodium salt emits toxic fumes of arsenic.

ChEBI: Sodium dihydrogen arsenate is an inorganic sodium salt that is the monosodium salt of arsenic acid. It has a role as a carcinogenic agent. It contains an arsenate(1-).
