Question
The correct statement(s) for orthoboric acid is/are
Options
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
Solution
H3BO3 + H2O ⇋ B(OH)4+ + H+
In boric acid, planar H3BO3 units are joined by hydrogen bonds to give layered structure.
