AI Generated Solution

To detect \( \text{SO}_3^{2-} \) (sulfite) in the presence of \( \text{SO}_4^{2-} \) (sulfate), we can follow these steps: ### Step-by-Step Solution: 1. **Precipitation with Barium Chloride**: - When barium chloride (\( \text{BaCl}_2 \)) is added to a solution containing both \( \text{SO}_3^{2-} \) and \( \text{SO}_4^{2-} \), a white precipitate forms. - The precipitate from \( \text{SO}_3^{2-} \) is barium sulfide (\( \text{BaSO}_3 \)), and from \( \text{SO}_4^{2-} \) it is barium sulfate (\( \text{BaSO}_4 \)). ...
