KOH+Cl2-----> KClO3+KCl+H2O
Balance using oxidation number method. Plz answer immediately.
Oxidation half reaction:
To balance oxidation number, we add 5e- to the right side
..............................................................................(i)
Reduction half reaction:
To balance oxidation number, we add 1 e- to the left side
...............................................................................(ii)
Now multiply (ii) equation by5 and then add (i) and (ii) equation
Now to balance all other atoms of complete disproportionation reaction:
3Cl2 + 6KOH KClO3 + 5KCl + 3H2O
