Balanced dissolution expression of Al (NO3) 3 (s)

Al (NO₃) ₃ (s) → Al⁺³ (aq) + 3NO⁻³ (aq)

Explanation:

To answer the question we need to ask ourselves the following;

What is a dissolution reaction?

Dissolution reactions are types of reactions in which solutes either in liquid, solid or gaseous form are dissolved in solvent such as water to form solutions.

What happens when a salt or a compound dissolves in water?

When a soluble salt or compound dissolves in water it ionizes to form ions. For example, Al (NO₃) ₃ is a soluble salt, therefore, when dissolved in water it dissolves completely into aluminium ions and nitrate ions. Therefore, the balanced dissolution equation for Al (NO₃) ₃ is;

Al (NO₃) ₃ (s) → Al⁺³ (aq) + 3NO⁻³ (aq)
