H_3BO_3 accepts hydroxide ion from water as shown below H_3BO_3(aq)+H_2O(l) leftrightarrow B(OH)_4^(-) + H^+ Predict the nature of H_3BO_3 using lewis concept. |

Answer» Solution :Boric acid is also calledas hydrogen BORATE or orthoboric acid . It is a weak MONO basic LEWIS acid of BORON and it is written as `B(OH)_3`. It accepts hydroxyl `(OH^-)` ion from water.It does not dissociate to give hydronium `(H_3O^+)` ion rather forms metaborate ion and this ion in turn give `H_3O^+` ion. `B(OH)_3+H_2O leftrightarrow [B(OH)_4]^-+ H_3O^+` HENCE it is considered as weak acid. |
