number of fatalities they had caused. A hydrated potassium antimonyl tartrate called “tartar emetic” is currently used in medicine as an expectorant, diaphoretic, and emetic. The maximum tolerable concentration of antimony dust in air is about the same as for arsenic, 0.5 milligram per cubic ...
1. Thermal decomposition of certain salts, such aspotassiumchlorate or potassium nitrate: The decomposition of potassium chlorate is catalyzed by oxides of transition metals;manganesedioxide (pyrolusite, MnO2) is frequently used. The temperature necessary to effect the evolution of oxygen is reduced from...
