Question

Assertion (A): The strength of the acid or the base decreases with dilution.

Reason (R): lonization of an acid or a base increases with dilution

Answer 1

Answer:

Both A and R are true and R is the correct explanation of A

Answer 2

Answer:

Assertion and reason both are correct. But reason is not the right explanation of the assertion.

Explanation:

• The strength of the acid or the base decreases with dilution because the volume of solution will increase with dilution and the number of ions per unit volume will decrease. Therefore, the assertion is correct.
• Ionization of an acid or a base increases with dilution because the degree of ionization will increase with dilution. Therefore, the the reason is also correct.
• But the ionization of an acid or a base increases with dilution is not correct explanation for the strength of acid or base decreases with dilution.
