A metal sulphide A gives gas B with rott...

A metal sulphide A gives gas B with rotten egg smell and a colourless sulphate C, when treated with dil `H_2SO_4`. B reacts with `K_2Cr_2O_7//H^+` to form D, a white grey element. D burns in oxygen to yield E a colourless gas. If B is added to E, it gives D and a colourless liquid, which turns anhydrous `CuSO_4` blue. C gives precipitate with `NH_(3(aq))` or NaOH, which dissolves in excess of NaOH

A

`CuSO_4`

B

`BaSO_4`

C

`ZnSO_4`

D

`Na_(2)ZnO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((A))(Zns )+ H_2SO_4 rarr underset((B))(H_2S) + underset((C))(ZnSO_4)`
`H_2S + K_2Cr_2O_7 rarr underset((D))(S+Cr_2O_3)`
`S+O_2 rarr underset((E)) SO_2`
`H_2S + SO_2 rarr S + H_2O`
`CuSO_4 + H_2O rarr underset((Blue))(CuSO_4.) 5H_2O`
`ZnSO_4 + NaOH rarr underset((white))(Zn(OH)_2darr) overset(NaOH) rarr underset("(soluble)")(Na_2ZnO_2)`
