WebAlkenes react with potassium manganate(VII) solution in the cold. The colour change depends on whether the potassium manganate(VII) is used under acidic or alkaline … WebSo let's look at a different way to do it. In this case, we're going to use permanganate. So we take our alkene and then we take permanganate, MNO4 minus, so something like potassium permanganate. And usually you do this reaction in cold sodium hydroxide solution-- a cold aqueous solution of sodium hydroxide, so water's in there as well.
