In the reaction Mn(s) + Ti2+(aq) → Mn2+(aq) + Ti(s), which species is reduced?

Explanation:
Reduction is the gain of electrons, shown by a decrease in oxidation state. Here, Ti2+(aq) starts with an oxidation state of +2 and becomes Ti(s) with oxidation state 0, meaning it has gained electrons. Mn, on the other hand, goes from 0 to +2, so it loses electrons and is oxidized. Therefore, the species reduced is Ti2+(aq).
