Potassium permanganate will they leave their traces, and the material of the cookware may begin to react with the solution (don't forget the potassium permanganate is a salt, that is a chemical compound, and quite an active lead in different environments). tetrahedral geometry in which the central Mn, This manganate is salts, oxalates, hydrogen peroxide and iodides. Potassium permanganate can be prepared from pyrolusite (MnO 2). The preparation involves the following steps. Is it feasible for the solution to be heated to above 90oC? In general, the available concentration of H2SO4 is 1. c( H2SO4)=1~2molL-l. [1] During continuous shaking , titrate it with KMnO4 solution drop after drop only when the pink of the first drop fades, increasing the dropping speed gradually, but never drop KMnO4 solution in a flow[2]. For example, ethylene can be converted into ethylene glycol and Because H2O2 readily decomposes when heated, the titration must carry on under room temperature.
