(i) Which property of ammonia is illustrated by equation (c)?

(ii) What important fertiliser is prepared from equation (d)? State the conditions.

A gas 'P' gives dense white fumes with chlorine. It's aqueous solution gives a blue colour with copper (II) hydroxide. Give the name and formula of the gas P.

Ammonia solution in water gives a blue precipitate when it combines with a solution of copper salt. The blue precipitate further dissolves in excess of ammonia solution to give an azure blue solution. Explain with equation.

(a) What do you observe when ammonium hydroxide is added to the aqueous solution of :

(i) FeSO₄

(ii) Iron (III) chloride.

(iii) Lead nitrate

(iv) Zinc nitrate

(b) Write balanced equation for Q.8(a).
