تماشای ویدئو Make potassium permanganate از آی-ویدئو

We try out the classic reaction between manganese dioxide, potassium hydroxide and potassium nitrate by making them into a paste and then heating strongly. We macerate the product with hot water, then disproportionate it using sodium bicarbonate to convert it to permanganate. We then attempt to obtain solid crystals of the product (but without success), and finally we experiment to test its oxidising power.
