Abstract
Dissolution kinetics of glassy and crystalline As2S3 in aqueous sodium sulfide and hydroxide solutions was investigated. Glass, produced by rapid quenching contains frozen products of arsenic trisulfide dissoci ation - As4S4 and S. A strong change in the chemical behavior of g-and c-As2S3 has been found in its interaction with hydroxide ions. A mech anism of dissolving has been suggested.
