SUMMARY
The reaction between magnesium (Mg) and hydrochloric acid (HCl) results in the formation of magnesium chloride (MgCl2) and dihydrogen gas (H2). Magnesium acts as a reducing agent, undergoing oxidation to form Mg2+ ions while reducing H+ ions from the acid to produce hydrogen gas. The half-reactions involved are Mg → Mg2+ + 2 e- with a standard electrode potential of 2.37 V, and 2H+ + 2e- → H2 with a standard electrode potential of 0.0 V. This reaction is influenced by factors such as concentration and temperature.
