Ammonium salts on heating with slaked lime liberates a colourless gas `(X)`. Identify the correct statement for gas `(X)` and ammonium salt.

A

It turns red litmus blue and gives yellow ppt. with `Na_(3)[Co(NO_(2))_(6)]`

B

It turns filter paper moistened with mercurous nitrate black and gives intense blue coloured solution with `CuSO_(4)(aq)`

C

It when passed through Nessler reagent produces a brown colour ppt.

D

All of these

Text Solution

The correct Answer is:
4
`(1) NH_(3)` alkaline in nature turns and red litmus blue ,
`3NH_(4)Cl+Na_(3)[Co(NO_(2))_(2)]rarr(NH_(4))_(3)[Co(NO_(2))_(6)]darr("yellow")+3NaCl`.
`(2) 2HgNO_(3)+2NH_(3)rarrubrace(Hg(NH_(2))NO_(3)+Hg)_("black")+NH_(4)NH_(3),CuSO_(4)+4NH_(3)rarr[Cu(nh_(3))_(4)]SO_(4)("intense blue ")`
`(3)2K_(2)(HgI_(4))+NH_(3)+3KOHrarrHgOHgNH_(2)Idarr("brown")+7KI+2H_(2)O`
