Abstract
The simple optical cell described is useful for providing supplementary information on the evolution of gases during the electrolysis of fused salts or other electrolytes. Its use with PbS-PbCl2 and PbS-PbCl2-NaCl melts demonstrated that, for anodic sulphur gas production, residual gas evolution occurs, indicating the formation of a chemisorbed species as a reaction intermediate. Dissolution of the sulphur in the melt also takes place; its rate increases with increase in temperature and sulphide concentration.
