Question

Balance the equation using ion electron method i^- +clo3^- +h₂so₄ --> cl^- + h₂so4^- + i₂ + h₂o. Give full detailed explanation.

Answer 1

6I^- + ClO₃^- + 6H₂SO₄ = Cl^- + 3I₂ + 6HSO₄^- + 3H₂O

• In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. 
• Each of these half-reactions is balanced separately and then combined to give the balanced redox equation.
