Al (NO₃) ₃ (aq) + NaOH (aq) → Al (OH) ₃ (s) ↓ + 3NaNO₃ (aq)

Explanation:

Al³⁺ cation can generate a precipitate when it bonds to OH⁻ from a strong base but it is important to the base, not to be in excess.

When the OH⁻is in excess, the produced aluminium hydroxide will be soluble.

Al³⁺ (aq) + 3OH⁻ (aq) ⇄ Al (OH) ₃ (s) ↓ Kps
