I am having a problem with this
I have added L vit C (C₆H₈O₆) 1mg/ml to a solution of permnganate KMO₄ (0.005M) (at 4°C)
The mermenganate turned from purple to trensparent
I can't seem to find to right equilibre and how do i explain this result ( I did not add any acid slution, the ascorbic acid is acid thought!)

KMnO₄ + C₆H₈O₆ = K+ + C₆H₆O₆ + Mn₂+ + H₂O?

The explanation is : Permanganate is an oxidiser and Ascorbic acid a reducer. Colour turns from purple to colourless

Permanganate : MnO₄- + 8 H+ + 5 e- => Mn₂+ + 4 H₂O

Ascorbic acid: C₆H₈O₆ + 6 H₂O => 6 CO₂ + 20 H+ + 20 e-

Sum:

4 MnO₄- + 12 H+ + C₆H₈O₆ => 4 Mn₂+ + 6 CO₂ + 10 H₂O

H+ is donated from additional Acorbic acid.
