A gas 'P' gives dense white fumes with chlorine. Its aqueous solution gives a blue colour with copper (II) hydroxide. (a) Name the gas P. (b) Give its formula. (c) Give three uses of P.
A gas 'P' gives dense white fumes with chlorine. Its aqueous solution gives a blue colour with copper (II) hydroxide. (a) Name the gas P. (b) Give its formula. (c) Give three uses of P.
a) The Ammonia gas (P) gives white dense fumes with Chlorine. So the name of the gas is Ammonia.
b). The formula of the gas NH3
To add ammonia gas to Copper ion, it gives blue colour Copper(II) hydroxide
Cu+2(aq)+2NH3(aq)+3H2O(l)⇌ Cu(OH)2(s)+2NH+4(aq)
To add excess Ammonia with copper (II) hydroxide forms deep blue solution of a complex compound.
Cu(OH)2(s)+4NH3(aq)⇌ [Cu(NH3)4]+2(aq)+2OH−(aq)
c)Uses of ammonia
1. Used in the manufacturing of fertilisers
2. Used in the manufacturing of explosives
3. Used as a base and lab reagent
4. Used in the manufacture of nitric acid.
