The rate of reaction between arsenite and vanadate, catalyzed by osmium(VIII) was monitored using an automatic potentiostatic stat method. This was carried out by maintaining the preset potential of a platinum indicator electrode by addition of a 2 Â10 À3 M vanadate solution (titrant). The rate of a
