Permanganate redox reaction

Videonummer 11936396
Redox reaction between acidified potassium permanganate solution and hydrogen peroxide. The permanganate is acidified using sulphuric acid (1.00 M, 20.0 mL), before hydrogen peroxide solution (35%, 20.0 mL) is added. Initially the manganese is in the +7 oxidation state, making it a powerful enough oxidising agent to oxidise the hydrogen peroxide to oxygen gas, which is seen bubbling off. The manganese itself is reduced from the purple Mn(7+) state to the colourless Mn(2+) state, leaving the solution colourless.
