THE OXIDATION OF CARBON MONOXIDE BY SOLID PERMANGANATE REAGENTS: VII. THERMAL DECOMPOSITION OF SILVER PERMANGANATE

Abstract

The thermal decomposition in a vacuum at 100 °C of both whole and ground crystals of pure dry silver permanganate was followed by the measurements of increase in pressure and of loss in weight. The decomposition products were determined by analysis and calculations to be silver oxide, silver, manganese dioxide, silver permanganite, and oxygen. On the basis of chemical analysis the following mechanism of decomposition is proposed:(1)[Formula: see text](2)[Formula: see text](3)[Formula: see text]The reaction proposed in equation (1) goes to completion, while the reaction proposed in equation (2) goes to approximately 37.7% completion, and that in equation (3) goes to approximately 6.6% completion.
