Question

Hydrogen chloride dissolves in water to form an acidic solution.
Give three distinct tests (apart from using an indicator) you would carry out with this solution to illustrate the typical properties of an acid.

Answer 1

Tests for hydrogen chloride are -
(i) When silver nitrate solution is added to hydrochloric acid, it gives white precipitate of silver chloride.
(ii) When lead nitrate solution is added to it, it gives white precipitate of lead chloride.
(iii) Concentrated hydrochloric acid when added to oxidizing agents like manganese dioxide, lead dioxide etc., it liberates chlorine gas which is a greenish yellow,
pungent smelling gas.
