 Question:

In the formation of magnesium chloride (by direct combination between magnesium and chlorine), name the substance that is oxidized and the substance that is reduced.

Solution:

Magnesium is oxidised and chlorine is reduced.

Explanation:

Loss of electrons is oxidation and gain of electrons is reduction.

Since Magnesium loses electrons, it is oxidised and chlorine gains electrons, so it is reduced.
