Autocatalysis. Demonstration of autocatalysis using ethanedioate and manganate(VII) ions. Autocatalysis occurs when reaction products catalyse the reaction itself. In this case,a solution of potassium permanganate (purple) is added to a solution of ethanedioic acid (oxalic acid,colourless). One of the products,the manganese(II) ion,further catalyses the reaction,liberating large quantities of carbon dioxide and carbon monoxide gases | |
