How would you distinguish between dilute hydrochloric acid and dilute sulphuric acid using a solution of barium chloride?
Original Khojo Papers practice question — not from a past board paper.
Answer
Adding barium chloride solution to dilute sulphuric acid gives a white precipitate of barium sulphate that does not dissolve in dilute hydrochloric acid. Dilute hydrochloric acid gives no precipitate with barium chloride.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Silver nitrate solution does the opposite: it gives a white precipitate with the chloride and none with the sulphate.
