When `BaCl_(2)` is added to an aqueous salt solution , a white ppt. is obtained . The anion amoung `CO_(3)^(2-) , SO_(3)^(2-) and SO_(4)^(2-)` that was present in the solution can be

Explanation

To solve the problem, we need to analyze the reactions that occur when barium chloride (BaCl₂) is added to an aqueous solution containing the given anions: carbonate (CO₃²⁻), sulfite (SO₃²⁻), and sulfate (SO₄²⁻).

### Step-by-Step Solution:

1. **Identify the Reaction with Carbonate (CO₃²⁻)**:
- When BaCl₂ is added to a solution containing carbonate ions, the following reaction occurs:
\[
\text{BaCl}_2 + \text{CO}_3^{2-} \rightarrow \text{BaCO}_3 \downarrow + 2\text{Cl}^-
