Can you write the balanced chemical equation that describes the dissociation of the strong base of magnesium hydroxide in water?
Magnesium hydroxide is an ionic compound. It consists of Mg²⁺ ions and OH⁻ ions. Its formula is Mg(OH)₂.
When Mg(OH)₂ dissolves in water, the ions separate or dissociate from each other and go into solution.
But Mg(OH)₂ is not very soluble in water. An equilibrium is soon reached in which Mg²⁺ ions and OH⁻ ions leave the surface of the solid as fast as they return.
The dissociation is an equilibrium reaction. The equation is:
Mg(OH)₂(s) ⇌ Mg²⁺(aq) + 2OH⁻(aq)
