Balanced Equation: Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
Oxidation: Magnesium (Mg) is oxidized. Magnesium atoms lose two electrons to become magnesium ions (Mg2+). This can be represented as: Mg(s) → Mg2+(aq) + 2e-
Reduction: Hydrogen ions (H+) from hydrochloric acid are reduced. Hydrogen ions gain two electrons to form hydrogen gas (H2). This can be represented as: 2H+(aq) + 2e- → H2(g)
Therefore, magnesium is oxidized (loses electrons) and hydrogen ions are reduced (gain electrons).
