Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): An aqueous solution of KOH when used for volumetric analysis, its concentration should be checked before the use. Reason (R): On aging, KOH solution absorbs atmospheric CO 2. In the light of the above statements, choose the correct answer from the options given below :

Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

KOH absorb CO 2 So its concentration should be checked.

(A) is correct but (R) is not correct

(A) is not correct but (R) is correct

Both $(A)$ and $(R)$ are correct but $(R)$ is not the correct explanation of $(A)$

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

$K O H$ absorb $C O_{2}$
So its concentration should be checked.

(A) is correct but (R) is not correct

(A) is not correct but (R) is correct

Both (A) and (R) are correct but (R) is not the correct explanation of (A)

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