What happens when `SO_2` gas is bubbled through an aqueous solution of copper sulphate in the presence of potassium thiocyanate?

Explanation

To solve the question of what happens when \( SO_2 \) gas is bubbled through an aqueous solution of copper sulfate in the presence of potassium thiocyanate, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Copper sulfate (\( CuSO_4 \))
- Potassium thiocyanate (\( KSCN \))
- Sulfur dioxide (\( SO_2 \))
- Water (\( H_2O \)) (since the solution is aqueous)
