Assertion : (III) is not precipitated as sulphide when in its alkaline solution is passed.
Reason : The concentration of ion in alkaline medium is inadequate for precipitation.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
C. If assertion is true but reason is false
Step-by-step solution
(III) is a basic radical of IIB group for which group reagent is in presence of dilute . It is necessary to maintain the proper hydrogen ion concentration for the precipitation of IInd group cations and to check the precipitation of IV group cations.
