Which of the following statements is not correct ?

Options

A. `underset(("borax"))(Na_2[B_4O_2(OH)_4].8H_2O + 2HCl) to 2NaCl + 4H_3BO_3 + 5H_2O`
B. `2BN + 6H_2O to 2H_3BO_3 + 2NH_3`
C. `H_3BO_3 underset(-H_2O)overset(375K)to underset(("metaboric acid"))(HBO_2,) 4HBO_2 underset(-H_2O)overset(435K)to underset(("tetraboric acid"))(H_2B_4O_7,) H_2B_4O_7 underset(-H_2O)overset("red heat")to underset(("Boric oxide"))(2B_2O_3)`
D. `H_3BO_3` is a weak monobasic acid as it liberates hydrogen ions as `H_3BO_3 to H^(+) + H_2BO_3^(-)`

Answer

D

Explanation

`H_3BO_3` is a weak monobasic acid. It does not liberate `H^(+)` but accepts `OH^(-)`. It is Lewis acid.
`B(OH)_3 + H-2O to [B(OH)_4]^(-) + H^(+)`
