Don't use hot water to dilute potassium permanganate

Don't use hot water to dilute potassium permanganatehas an efficacy of disinfection effect due to potassium permanganate, whether at home or hospital, are standing. However, very particular about preparation of potassium permanganate solution, requires extra attention. First, the concentration to master the accurate, concentration is too high can cause corrosion of skin ulcers. Test simple method is direct observation of the concentration of solution of color, rose red. Secondly, disinfection must reach 5 minutes long, slow release of oxygen by potassium permanganate, considerable time is required to kill bacteria, and the preparation of aqueous solution of good usually can be saved only about two hours. When when the solution becomes purple-brown, the disinfection of lost, best used with the distribution. Finally, the preparation of potassium permanganate when application of cold boiled water, hot water preparation solution makes the oxygen ion the prompt release of decomposition, thus losing bactericidal action.
