Question

Assertion: $C{e}^{4+}$ is used as an oxidizing agent in volumetric analysis.
Reason: $C{e}^{4+}$ has a tendency to attain its $+3$ oxidation state.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct and (R) is not the correct explanation of (A)
• C. (A) is correct, but (R) is incorrect
• D. (A) is incorrect , but (R) is correct

Answer 1

The correct option is A Both (A) and (R) are correct and (R) is the correct explanation of (A)

$C{e}^{4+}$ has the tendency to attain $+3$ oxidation state due to which cerric sulphate, $\left[Ce\right(S{O}_4{)}_2]$ is widely used as an oxidising agent in volumetric analysis.
