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.

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
