The gas `'G'` will show which of the following properly ?

A

It turns lead acetate filter paper black.

B

It turns acidified `K_(2)Cr_(2)O_(7)` filter paper green.

C

It produces purple colouration on filter paper moistened with sodium nitroprusside already made alkaline with sodium hydroxide.

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
(A)`Pb^(2+)+H_(2)StoPbS darr("black")+2H^(+)`.
(B)`Cr_(2)O_(7)^(2-)+3H_(2)S +8H^(+) to 2Cr^(3+)`(green colour solution) +`3S darr +7H_(2)O`
( C)`S^(2-)+[Fe(CN)_(5)NO]^(2-)to [Fe(CN)_(5)NOS]^(4-)` (purple colouration).
Reactions :`Na_(2)SO_(4)+BaCl_(4)toBaSO_(4)darr+NaCl`
`BaSO_(4)+4C+Na_(2)CO_(3)overset("Fuse")toNa_(2)S+BaCO_(3)darr +4CO uarr`
`Na_(2)S +H_(2)SO_(4) to Na_(2)SO_(4)+H_(2)S`
