Expert Answer:

Citric acid turns potassium permanganate from purple to colourless because it is a reducing agent.

KMnO4 will oxidize citric acid  to CO2 and  H2and itself will turn into almost colorless Mn(2+) (in acidic environment), or, into brown MnO2 precipitate.
      OR 
 
C6H807 +  KMnO4  +    H? 6CO2  + H2O  + MnO2
