Lokash is a social worker. A milkman in the village has been complaining that a factory in his nearby area dumps chemical waste in his field which has become a major cause of decreasing producutivity. Lokesh visited that place and found after analysis that the major waste was potassium permanganate which id being absorbed by the soil. He advised the factory people that they should potassium permanganate solution before dumping it into the drain. Comment in brief : (i) About the value/s displayed by Lokesh. (b) Write balanced chemical equations for the two reactions showing oxidizing nature of potassium permanganate.
