Which is oxidized, reduced, the oxidizing agent and the reducing agent

Question

3Mg+ 2AlBr₃ → 3MgBr₂ + 2Al

Oxidized:

Oxidizing Agent:

Reduced:

Reducing Agent:

Answer 1

Look at the oxidation numbers for each element on both sides of the equation

Mg on left is zero and Mg on the right is 2+. Mg has lost electrons and so is oxidized = reducing agent

Al on left is 3+ and Al on right is zero. Al has gained electrons and so is reduced = oxidizing agent

Oxidized: Mg

Oxidizing Agent: Al

Reduced: Al

Reducing Agent: Mg
