Potassium permanganate potassium permanganate) and the name (" HuiMengYang ", "PP powder", it is a kind of common strong oxidizer, under normal temperature for dark-purple flake crystals, easy to see light decomposition: 2KMnO 4 (s) - K2MnO hv - 4 (s) + MnO 2 (s) + O 2 (g), reason need to avoid light stored in shady and cool place, with no combustible and metal powder with put. Potassium permanganate with manganese dioxide as raw material producing, are widely used in industry, such as disinfectant, bleach in laboratory, potassium permanganate because of its strong oxidizing and solution colors bright-coloured and is used in the physical appraisal, acidic potassium permanganate solution is REDOX titration important reagents.
