Arsenic acid, trisodium salt (7631-89-2)

 Arsenic acid, trisodium salt ,its cas register number is 7631-89-2.It also can be called Arsenic(V) acid, trisodium salt, heptahydrate (1:3:7) ; Sodium arsenate ; Monosodium arsenate and Arsenate, sodium .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.When heated to decomposition, Arsenic acid, trisodium salt (CAS NO.7631-89-2) emits toxic fumes of arsenic.
