We have to balance the given redox equation by using H2O(l) and H+(aq) and determine their coefficients in the balanced chemical equation.

We will start by splitting the equation into two half-reactions and then determine which halves are reduction and oxidation halves.

Sn2+(aq) → Sn4+(aq)

Recall that the charge on a metal cation is its oxidation state.

The oxidation state of Sn is increasing from +2 to +4 therefore, this is the oxidation half-reaction.

SO42-(aq) → H2SO3(aq)

Since we have already determined the oxidation half-reaction, this one must be the reduction half-reaction.
