Question

Using Ion electron method balance the reaction in basic medium MnO4^-+I------>MnO2+IO3^-​

Answer 1

The complete equation will be :

MnO⁴⁻ + I⁻ + H₂O  ====== > MnO₂ + IO³⁻ + OH⁻

In order to balance the equation proceed these steps :

Add 2 beside MnO⁴⁻ .

Add 2 beside MnO₂ so as to balance the Mn .

Add 2 beside OH⁻ .

Count and see whether they are balanced or not .

Mn = 2

O = 8 + 1 = 9

I = 1

H = 2

This is balanced on both sides .

BALANCED EQUATION :

2 MnO⁴⁻ + I⁻ + H₂O  ====== > 2 MnO₂ + IO³⁻ + 2 OH⁻
