Thanks Yogita, but in the products, will not the water (H2O) and manganese oxide (MnO2) react with each other to form Manganese hydroxide [Mn(OH)2] with hydrogen?

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

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

C₆H₈0_{7 +}KMnO_{4 +}H⁺→ 6CO₂ + H₂O + MnO₂

1Thank You
