Abstract
A process for producing arsenous acid is disclosed. The reactants include an organic solvent containing 5 valent arsenic, a reducing agent and an additional component selected from the group consisting of water and an aqueous solution. The organic solvent containing 5 valent arsenic contacts and reacts with the reducing agent in the presence of the water or aqueous solution in order to directly produce arsenous acid from the organic solvent containing 5 valent arsenic. The process is a simple and economical process for producing arsenous acid.
