2-MERCAPTO- AND 2-METHYL-BENZIMIDAZOLES AS REAGENTS FOR SILVER

2-Mercapto- and 2-methyl-bentimidazoles have been found to be useful reagents for gravimetric estimation of silver in ammoniacal medium in the presence of other metals by masking them with appropriate reagents. The silver salts of these reagents are stable towards light, and beat, and determination can be made rapidly.
