Potassium permanganate is an ionic compound consisting of a potassium cation (K+) and permanganate anion (MnO 4-). Potassium permanganate is an oxidant, but a poor disinfectant. This is an exothermal reaction and potassium is heated to such an extend that it burns a purple flame. .You can use potassium permanganate crystals to purify water. Dropping crystals of potassium permanganate into a tall column of water leads to the slow dissolution and diffusion of the potassium permanganate throughout the column over a semester's time. Continuous exposure to 0.5 mg KMnO4 or exposure to 1 or 2 mg KMnO4/L on alternate days did not cause a significant incr in manganese in axial muscle or liver tissue. Potassium Permanganate CAS-No. Low oxygen conditions can occur following treatment.Be prepared to aerate after treatment.Frequent treatment can harm fish. Follow the manufacturer's instructions for dose when treating water for odor and taste. Pour hot water into the petri disk until full 3. The density of the substance is 2.703 g / cm. Please reconnect, Authors & In permanganate anion (MnO 4-) the manganese atom is bonded with four oxygen atoms through three double bonds and one single bond. It reacts with water more rapidly than does sodium, which is placed higher in the periodic chart. This usually means adding 3-4 crystals per liter of water.
