(a) State your observation for the following reactions:
(1) Hydrogen chloride gas is passed through lead nitrate solution and the product thus
forned is heated.
(ii) Sodium sulphide is treated with dilute hydrochloric acid.
(iii) Excess of ammonium hydroxide is added to the precipitate obtained on reacting
silver nitrate solution with hydrochloric acid.
(iv) Differentiate between Carbon tetra chloride and Sodium chloride on the basis of
Solubility in water and Volatility.

Answer:
1. Hydrogen chloride gas is passed through lead nitrate solution and the product thus
forned is heated.
ans=Dilute Hydrochloric acid is added to Lead nitrate Solution and the mixture is heated. When dil. HCl is added to lead nitrate solution and heated, it forms a white precipitate of lead chloride.
2. Sodium sulphide is treated with dilute hydrochloric acid.
When dilute hydrochloric acid reacts with sodium sulphite, sulphur dioxide gas is evolved. The reaction when hydrochloric acid reacts with sodium sulphite, it forms sodium chloride and sulphur dioxide which gives the smell of burning sulphur.
3. Excess of ammonium hydroxide is added to the precipitate obtained on reacting
silver nitrate solution with hydrochloric acid.
Ammonium hydroxide (NH4OH), commonly known as ammonia or ammonia water is a solution of ammonia in water. ... Silver chloride reacts with ammonium hydroxide and yields diamine, silver chloride and water.
4. Differentiate between Carbon tetra chloride and Sodium chloride on the basis of
Solubility in water and Volatility.
Tetrachloride and Sodium Chloride? ... The key difference between carbon tetrachloride and sodium chloride is that carbon tetrachloride is a covalent chemical compound whereas sodium chloride is an ionic chemical compound.
