NEETChemistryp Block Elements (Group 13 & 14)
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.
Options
- ABoth A and R are correct and R is the correct explanation of A
- BBoth A and R are correct but R is NOT the correct explanation of A
- CA is correct but R is not correct
- DA is not correct but R is correct
Correct answer
A. Both A and R are correct and R is the correct explanation of A
Step-by-step solution
Boric acid is a weak acid because it does not completely ionize in water or other aqueous solution. It is not able to release H + ions on its own because firstly it receives hydroxide ions OH - from water molecule in order to complete its octet and then it releases H + ions.
