Question

Assertion :On dilution of a concentrated solution of $C{H}_{3}COOH$, the concentration of $\left[H^{+}\right]$ decreases . Reason: The increase in the volume is more than the increase in degree of ionization.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

On dilution of a concentrated solution of $C{H}_{3}COOH$, the concentration of $\left[H^{+}\right]$ decreases .
The degree of the ionization increases. Hence, the number of hydrogen ions increases. But the number of hydrogen ions per unit volume decreases.
The increase in the volume is more than the increase in the degree of ionization.
Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
