Chemistry · EQUILIBRIUM

हिन्दी

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Water acts as a Bronsted base in the reaction with \( \text{HCl} \), but acts as a Bronsted acid in the reaction with \( \text{NH}_3 \). Reason (R): Water has a high dielectric constant of 80. In the light of the above statements, choose the correct answer from the options given below:

  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.

Correct answer · Option 2

Both (A) and (R) are true but (R) is NOT the correct explanation of (A).

Explanation

Both statements are correct facts, but water's amphoteric behavior is due to its ability to donate and accept protons, not directly because of its dielectric constant.
