Which of the following statements about H3BO3 is not correct ? [1994]a...
Explanation:
Statement Analysis:
- Statement (a): It is a strong tribasic acid
- Statement (b): It is prepared by acidifying an aqueous solution of borax
- Statement (c): It has a layer structure in which planar BO3 units are joined by hydrogen bonds
- Statement (d): It does not act as a proton donor but acts as a Lewis acid by accepting a lone pair of electrons
Correct Statement:
The statement that is not correct is option 'A' which mentions that H3BO3 is a strong tribasic acid.
Explanation:
- Boric acid (H3BO3) is actually a weak tribasic acid, not a strong tribasic acid. It dissociates partially in water to give H+ ions, making it a weak acid.
- Boric acid is prepared by acidifying an aqueous solution of borax, as mentioned in statement (b).
- The structure of boric acid does have a layer structure in which planar BO3 units are joined by hydrogen bonds, as stated in statement (c).
- Boric acid does not act as a proton donor like typical acids but acts as a Lewis acid by accepting a lone pair of electrons, as mentioned in statement (d).
Therefore, the correct statement is that boric acid (H3BO3) is a weak tribasic acid, not a strong tribasic acid.
