Write balanced chemical equations for these equations :
Aluminium sulphate reacts with sodium hydroxide to form a precipitate of aluminium hydroxide while the solution after the reaction is found to contain sodium sulphate.

Explanation

To write the balanced chemical equation for the reaction between aluminium sulphate and sodium hydroxide, we will follow these steps:

### Step 1: Write the formulas of the reactants
- **Aluminium Sulphate**: The formula for aluminium sulphate is \( \text{Al}_2(\text{SO}_4)_3 \).
- **Sodium Hydroxide**: The formula for sodium hydroxide is \( \text{NaOH} \).

### Step 2: Identify the products
The reaction produces:
