The correct statement (s) for orthoboric acid is/are

A

It behaves as a weak acid in water due to self-ionization

B

Acidity of its aqueous solution increases upon addition of ethylene glycol

C

It has a three-dimensional structure due to hydrogen bonding.

D

It is a weak electrolyte in water

Text Solution

Verified by Experts

The correct Answer is:
B, D

a.`H_(23)BO_(3)` does not ionize on over rather it is Lewis acid due to electron deficiency on `B` it accepts `-OH` from water
`H_3BO_(3) +H_(2)OhArr B(OH)_(4)^(-)+H^(+)`
(b) c. It has a planar sheet like structure due to the hydrogen bonding. It has three-dimensional structure.
d.`H_(3)BO_(3)` is a weak electrolyte in water.
