Give three distinct test [apart from using an indicator] you would carry out with a solution of HCl to illustrate the typical properties of an acid.

Answer»

Three tests are:

HCl gas gives thick white fumes of ammonium chloride when glass rod dipped in ammonia solution is held near the vapors of the acid.

NH3 + HCl ⟶ NH4Cl

With silver nitrate HCl gives white precipitate of silver chloride. The precipitate is insoluble in nitric acid but soluble in ammonium hydroxide.

AgNO3 + HCl ⟶ AgCl + HNO3

A greenish yellow gas is liberated when concentrated hydrochloric acid is heated with oxidizing agent like manganese dioxide.

MnO2 + 4HCl ⟶ MnCl2 +2H2O + Cl2
