1.	(a) What is the action of litmus on: (i) Dry ammonia gas (ii) Solution of ammonia gas in water (b) State the observations you would make on adding sodium hydroxide to aqueous solution of : (i) Ferrous sulphate (ii) Aluminium chloride Give balanced chemical equations.
Answer» SOLUTION :(a) (i) No change in colour (ii) red litmus turns BLUE (b) (i) `2NaOH(aq)+FeSO_4(aq) to FE(OH)_2(s)+Na_2SO_4` Sodium hydroxide Ferrous sulphateFerrous hydroxide Sodium sulphate (III) `3NaOH(aq)+AlCl_3(aq) to AL(OH)_3(s)+ NaCl(aq)` Sodium Hydroxide Aluminium chloride Aluminium Hydroxide Sodium chloride
