ON adding NaOH to ammonium sulphate, a colourless gas with pungent odour is evolved which forms a blue coloured complex with `Cu^(2+)` ions. Identify the gas.

Text Solution

Verified by Experts

A colourless gas with pungent odour is ammonia. The following reactions are carried out.
`(NH_(4))_(2)SO_(4)+2NaOH overset(Delta)rarr 2NH_(3)+2H_(2)O+Na_(2)SO_(4)`
`underset((aq))(4NH_(3))+underset((aq))(Cu^(2+))rarr underset("Blue coloured complex")([Cu(NH_(3))_(4)]^(2+))`
