Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Boric acid is a weak acid
Reason R: Boric acid is not able to release \(H^+\) ion on its own. It receives \(OH^–\) ion from water and releases \(H^+\) ion.
In the light of the above statements, choose the most appropriate answer from the options given below.

• A. Both A and R are correct and R is the correct explanation of A.
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Answer 1

The Correct Option is A

\(H_3BO_3+H_2O ⇌ [B(OH)_4]^−+H⨁\)

Boric acid is not able to release H+ ion on its own. 

It receives \(OH^–\) ion from water and releases \(H^+\) ion as shown in the above reaction.

Hence, Both A and R are correct and R is the correct explanation of A.
