Question

Balance these redox reactions by the half-reaction method

Sn²⁺ → Sn + Sn⁴⁺

Answer 1

This is a disproportionation reaction in which Sn²⁺ is both oxidized and reduced.

Sn²⁺ ==> Sn + Sn⁴⁺ ... unbalanced equation

Sn²⁺ + 2e- ==> Sn ... balanced reduction half reaction

Sn²⁺ ==> Sn⁴⁺ + 2e- ... balance oxidation half reaction
