Question 2(2014)

Distinguish between the following pairs of compounds using the test given within brackets: Dilute sulphuric acid and dilute hydrochloric acid [using barium chloride solution]

Answer

Barium chloride soln. reacts with dilute sulphuric acid to give a white ppt. of barium sulphate (BaSO4) but with dilute hydrochloric acid no white ppt. is produced since barium chloride is soluble in dil. sulphuric acid.

H2SO4 (dil.) + BaCl2 (aq.) ⟶ 2HCl + BaSO4 ↓ [white ppt. formed]

HCl (dil.) + BaCl2 (aq.) ⟶ No reaction
