✦ Synopsis

The current/voltage curves for several concentrations of tetrachloroplatinite in solutions of perchloric acid and sodium perchlorate have been measured using stationary electrode polarogrsphy and sweep rates in the range O*Ol-1.0 V/s.

The polarogrsms show two cathodic peaks. The tit is due to the reduction of mercurous chloride. The second appears in the potential range +O*l to -0*2V(sce), depending on sweep rate, and is caused by the reduction of the platinum (II) complex. The values of k and a for the reduction process have been determined in both neutral and alkaline solutions. In acid solutions the evolution of hydrogen causes a disturbance in the measurements.
