Abstract
Investigation of the physicochemical properties of the H3AsO4–H2O system is of great importance, since arsenic acid is involved in the electrochemical synthesis of arsine, which is used to produce AIIIBV semiconductors. The surface tension of arsenic acid solutions of various concentrations in a wide temperature range (20–80°C) was measured by the stalagmometric method. It has been determined that arsenic acid in an aqueous solution is a surface-inactive substance because, with increasing concentration of H3AsO4 in solution, its surface tension increases.
