WebMar 7, 2014 · Therefore, the number of electrons transferred from oxidized species per mole K M n O X 4 (5 electrons) is the largest, and the least amount of K M n O X 4 is needed for the reaction with a certain amount of alcohol. This makes oxidation in acidic medium the best choice for economic reasons. WebMay 30, 2008 · Results reveal that significant MnO2 production and inhibition of TCE oxidation were not observed under acidic (pH 2.1) or slightly acidic conditions (pH 6.3). However, significant reduction of KMnO(4) to MnO2 would occur under alkaline condition (pH 12.5), and this caused the decrease in TCE oxidation rate.
