Boric acid in aqueous solution in presence of glycerol behaves as a strong acid due to the formation of
(a)an anionioc metal - chelate
(b)borate anion
(c)glycerate ion
(d)a charge transfer complex
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
B(OH)₃ is a weak Lewis acid; cis-diols such as glycerol chelate the tetrahedral borate to form a stable anionic bis-chelate, [B(diolate)₂]⁻, releasing H⁺ and making the solution strongly acidic (titratable).
