Title: How to make pottasium permanganate crystals from solution
Post by: eric2011 on 21/06/2021 13:39:37

Hi

I have a solution of pottasium permanganate which is pink in color. How can I make crystals out of that solution

Gracias

The obvious answer is to evaporate off the water. If the solution is only pink then you have very little permanganate present.
Strong solutions are practically black.

So, at best, you will get very little crystalline material.

Also, if the solution contains anything else, it will be concentrated along with the permanganate, so you will get an impure product.
And permanganates are not very stable, it is likely that much of the material will decompose when you try to crystallise it
