Barium chloride solution was used to test for sulfate ions in the presence of dilute hydrochloric acid. What color precipitate would
form if sulfate ions were present?

Answer:

white

Explanation:

A white precipitate of barium sulfate forms if sulfate ions are present. The hydrochloric acid is added first to remove any carbonate ions that might be present - they would also produce a white precipitate, giving a false positive result. Barium nitrate solution can be used instead of barium chloride solution
