sulphuric acid‚ H2SO4 and potassium permanganate‚ KMnO4 is added into glucose with different concentration and the time taken for the purple pink colour of potassium permanganate solution to change to colourless is recorded. This is because glucose donates electrons to the permanganate ions‚ causing it to change colour (Kolej Mara Banting – Students’ Handbook for Biology HL Year 1). MnO4- + 8H+ + 5e- ------> Mn2+ + 4H2O
