Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): According to Ostwald's dilution law, the degree of ionization of a weak electrolyte is inversely proportional to the square root of its concentration. Reason (R): When a 0.1 ~M solution of a weak acid is diluted to 0.01 ~M , its degree of ionization ( ) increases. In the light of the above statemen

Step-by-step solution

Assertion (A) is true because Ostwald's dilution law states that for a weak electrolyte, the degree of ionization = K_ a C , which means 1 C . Reason (R) is also true because as concentration decreases from 0.1 ~M to 0.01 ~M (dilution), the degree of ionization increases. However, Reason (R) is merely a specific observation or consequence of Ostwald's dilution law, not its explanation. The law itself is derived from the equilibrium constant expression. Therefore, both Assertion and Reason are true, but Reason is no
