✦ Synopsis

The polarographic reduction of 1-phenyl-3-amino%rylazo-pyrazole-5-one and its arylazo substituted derivatives is studied in Britton-Robinson buffers (pH 3-IO), containing 40Β°k dimethyl formamide. The compounds exhibit a single wave in acidic solutions and two waves in alkaline solutions. A plausible mechanism has been suggested on the basis of number of protons and electrons involved in the reduction.

The polarographic behaviour of ethyl thioglycollate HS-CHICOOCBH, has been studied in 40% ethanol media at the dme in the pH range 150-12.66, using different buffers in presence of O-1. M KN08 and 0.002% Triton X-100. A single well defined irreversible anodic wave was obtained, which shifted towards
