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.
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.
- Both A and R are correct and R is the correct explanation of A.
- Both A and R are correct but R is NOT the correct explanation of A
- A is correct but R is not correct
- A is not correct but R is correct
The Correct Option is A
Solution and Explanation
\(H_3BO_3+H_2O ⇌ [B(OH)_4]^−+H⨁\)
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.
