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. WebSteps of preparation of 1% alkaline potassium permanganate solution. Dissolve 1 gram of solid KMnO 4 in 100 ml of distilled water to produce a 1% potassium permanganate solution. Add 10 grams of anhydrous sodium carbonate (NaCO 3) to the KMnO 4 solution and the stoppered bottle is shaken until fully dissolved and mixed.
