Chemical Reactions Involving Magnesium Nitride

Chemical Reactions Involving Magnesium Nitride

Magnesium nitride (Mg3N2) is a binary compound composed of magnesium (Mg) and nitrogen (N). It is prepared by heating magnesium with molten nitrogen. This compound can be involved in various chemical reactions depending upon the conditions applied to it, including the addition of acids, bases, water, or heat. Let's explore these reactions in detail:

Formation of Magnesium Hydroxide and Ammonia

When liquid water (H2O) is added to magnesium nitride (Mg3N2), the products are magnesium hydroxide (Mg(OH)2) and ammonia (NH3). The balanced chemical equation for this reaction is:

Mg3N2(s) + 6H2O(l) → 3Mg(OH)2(s) + 2NH3(g)

Ammonia Production

If dry ammonia (NH3) gas is produced when the mixture is heated, the balanced chemical equation is:

Mg3N2(s) + 3H2O(l) → 3(MgO(s) + 2NH3(g))

Reheating Reactions

When solid magnesium hydroxide (Mg(OH)2) is heated, it can be decomposed into magnesium oxide (MgO) and water (H2O). This reaction is described by the equation:

Mg(OH)2(s) → MgO(s) + H2O(l)

Reaction with Water

When magnesium nitride (Mg3N2) is reacted with water (H2O), it forms magnesium hydroxide (Mg(OH)2) and ammonia (NH3) gas. The balanced chemical equation for this reaction is:

Mg3N2(s) + 6H2O(l) → 3Mg(OH)2(s) + 2NH3(g)
