Question 22

Assertion (A): An electrolyte can be acid, base or salt.

Reason (R): An electrolyte is a substance which can conduct electricity in aqueous or molten state.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

Both A and R are true but R is not the correct explanation of A.

Explanation — Electrolytes include acids (like HCl), bases (like NaOH), and salts (like NaCl). Hence, assertion (A) is true.
Electrolytes conduct electricity in aqueous or molten states because they produce ions. Hence, Reason (R) is true.
The reason correctly describes what an electrolyte does, but it doesn’t directly explain why acids, bases, and salts are classified as electrolytes. Hence, both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
