Hello every one.
Im very interested in the synthesis of KMnO4 from Mno2, but i have a problems understanding the synthesis. First of all, i want to get KMnO4 fusing
MnO2 with KOH in presence of KClO3 AND KNO3, i mean two separate processes, one (1) using MnO2, KOH and KClO3 and other using (2) MnO2, KOH and KNO3.
i think i almost have a detailed procedure for (1), the problems comes from the (2) becaue there is not much info in the internet about it. Please,
someone of you can provides me a little of detailed info about it, i will very grateful.
Thanks.

That should get you started.
BTW, questions like this and anything without references belongs in the Beginnings section. I'll message a mod to move it for you.
Welcome to SM. Stick around, read the FAQ, browse the board (there is almost everything here) and have fun.

I understand your question is about synthesizing KMnO4 but I hope you're aware it can be purchased for water softener systems at hardware stores in
fairly large quantities. At least here in the US it can be.

You won't be able to make pure crystals. The best you can do is probably make a solution, but that would be fine if you're just using it to make
carboxylic acids or whatever.

There is the big thread over at the General forum

Make sure that you use KOH instead of NaOH like I did, or else you get no KMnO4. Perhaps the presence of Na+ interferes.
