In acidic medium, the balanced redox reaction between Iron II Sulphate FeSO and Potassium Permanganate KMnO is as follows:5 FeSO + 2 KMnO + 8 HSO 5 Fe SO + 2 MnSO + KSO + 8 HOHere's the step-by-step process to balance the redox reaction:1. Write the two half-reactions:Fe Fe Oxidation half-reaction MnO Mn Reduction half-reaction 2. Balance the atoms in each half-reaction:Fe Fe already balanced MnO + 8 H + 5 e Mn + 4 HO balanced 3. Balance the charges by adding electrons:Fe Fe + e balanced 4. Multiply the half-reactions by appropriate factors to equalize the number of electrons:5 Fe Fe + e 2 MnO + 8 H + 5 e Mn + 4 HO 5. Add the half-reactions and simplify:5 Fe + 2 MnO + 16 H 5 Fe + 2 Mn + 8 HO6. Add the spectator ions to complete the balanced equation:5 FeSO + 2 KMnO + 8 HSO 5 Fe SO + 2 MnSO + KSO + 8 HO
