Distinguish between the given pairs of compounds using the test given within brackets:
Dilute sulphuric acid and dilute hydrochloric acid (using barium chloride solution)
Solution
Sulphuric acid precipitates the insoluble sulphate of barium from the solution of barium chloride
BaCl2 + H2SO4 → BaSO4 + 2HCl
Dilute HCl does not react with barium chloride solution, and thus, no precipitate is produced in the reaction.
