Question

Balance the following Redox reaction, which occurs in Acidic solution: Mn2+ (aq) MnO4 (aq) + H,C204(aq) + CO2(aq)

Answer 1

steps to balance the redox is caution in acidir medium steps: write both half realtion seperately. steps: Balane the Elements except oft. step 3: Balance o by adding H₂O. stepy: Balonce H by adding it. steps: Balance charge by adding electrons steps: equate number of electrons in both half reaction by multiplying suitable number. stept: Add both half reaction to get final realtion to arrange HT & H2O. Steps: Mnoy- Mn2+ H₂ C20 u co2 Step 2: Mn is balanced balence carbon. Mnoy Home+ H2(204 - 2002 step3: Balancing o by adding H2o Mnoy Mn²+ + 4H₂O H₂ C204 2002 stupy: Balancing Mnoy +84t + 4H20 H₂ C204 -> 2202 + 2H+ Hydrogen by adding at. - Mn2t

> 2 Mm2t +8H₂O H₂c2oy +5H₂C2O 4 2mn2+ + 8 H₂O steps: Balance charge by adding electron. Mnoy +8Httsé Mn2+ + 4H₂O 2002 + 2Ht the steps: equate number of electrons by multiplying first reaution by 2 9 second reaction by s. 2M nou + 16H+ + loé - 5H₂C2O4 loco, tlout +loe Thentfore The balanced sealpon is: 2 mnou + 64+ +5H₂C2O4 2MM2+ +8+420 +1000,
