Answer

Mg is oxidized.

Sn²⁺ is reduced

Step-by-step explanation

Given equation:

Mg(s) + Sn²⁺(aq) → Mg²⁺(aq) + Sn(s)

An oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, it gets reduced. A reducing agent is a substance that causes reduction by losing electrons; therefore it gets oxidized.

From the given equation, the oxidation of Mg changes from 0 to +2, while the oxidation number of Sn changes from +2 to 0.

Therefore, Mg is oxidized, and Sn²⁺ is reduced.
