Vue d’ensemble

Boric acid is a weak monobasic acid, it accepts OH - ions, hence is a Lewis acid. In boric acid, B is sp 2 hybridized, forming a planar triangle structure. The principal oxide of boron, B 2 O 3 , is obtained as a vitreous solid by dehydration of boric acid at red heat.

Application

Boric acid was used as a constituent in mineral sacrificial paste. 1 It has been used as a buffer in electrodeposition of nickel. 2
