Consider the skeletal equation: Sn 2+ (aq) + Fe 3 + (aq) $\rightarrow$Sn 4+ (aq) + Fe 2+ (aq) When balanced, the equation will be:

The balanced equation requires equal numbers of electrons transferred. Sn 2+ loses 2 electrons to become Sn 4+ , and each Fe 3+ gains 1 electron to become Fe 2+ . Therefore, 2 Fe 3+ are needed for every Sn 2+ .
