Assertion:Sb(III) is not precipitated as sulphide when in its alkaline solution `H_(2)S` is passed.
Reason:The concetration of `S^(2)` ion in alkaline medium is inadequate for precipitation

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

if both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false.
Sb(III) is a basic radical of IIB group for which group reagent is `H_(2)S` in presence of dilute HCl. It is necessary to maintain the proper hydrogen ion concentration for the precipitation of IV group cations.
