Assetion : `Ce^(3+)` is used as an oxidizing in volumetric analysis.
Reason : The nubmer of uparied electrons in the following gaseous inon:
`Mn^(3+), Cr^(3+), V^(3+)` and `Ti^(3+)` are 4,3,2 and 1 respctively.

Options

A. If both assetion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are ture but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer

C

Explanation

Correct Reason: `Ce^(4+)` has the tendency to change to `Ce^(3+)` (as `+ 3` oxidation state is more stable).
