Episode 7: How to make Potassium Persulfate

Hello Chemists. Today I will show you how to make Potassium Persulfate. 

First you will need some Ammonium Persulfate. This is very easy to find and can be purchased at any electronic store (Jaycar, Dick Smith, Radioshack etc) as PCB etch. You will also need Potassium Chloride which can be found as No-Salt

Mix them stoichiometrically and filter off the Potassium Persulfate.

Keep the clear solution as that has useful ammonium chloride
