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 when for volumetric analysis, its concentration should be checked before the use.
Reason (R) : On aging, solution absorbs atmospheric .
In the light of the above statements, choose the correct answer from the options given below.
Options
- A(A) is not correct but (R) is correct
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- CBoth (A) and (R) are correct and (R) is the correct explanation of (A)
- D(A) is correct but (R) is not correct
Correct answer
C. Both (A) and (R) are correct and (R) is the correct explanation of (A)
Step-by-step solution
absorb based on the following reaction:
Thus, concentration of Carbon dioxide decreases over time, prior to volumetric analysis concentration of potassium hydroxide should be checked.
Thus, concentration of Carbon dioxide decreases over time, prior to volumetric analysis concentration of potassium hydroxide should be checked.
