Answer»

SOLUTION :USES of `NH_3`
(i) It is used in the manufacturingof NITRIC acid
(ii) It is used as a laboratory reagent.
Reaction of `NH_3` with
(i) `H_2O : NH_3 + H_2O iff NH_(4)^(+) + OH^(-)`
(ii) `HCl : NH_3 + HCl to NH_4Cl`
(iii) `FeCl_3 (aq)`
`FeCl_3 + 3H_2O + 3NH_3 to Fe(OH)_3 DARR + 3NH_4Cl`
