Description

General description

Boric acid is a weak monobasic acid, it accepts OH^- ions, hence is a Lewis acid. In boric acid, B is sp² hybridized, forming a planar triangle structure.The principal oxide of boron, B₂O₃, is obtained as a vitreous solid by dehydration of boric acid at red heat.

Application

Boric acid can be used as fungicide, bactericide, antiseptic, insecticide. Large scale use in glass industry as flame retardant, in buffer solutions.
Boric acid finds uses in several areas; such as

• In glass fibres, to enhance its resistance and color
• In glazing ceramic wares
• As a condensing agent, chemical intermediate and as a precursor for preparation of borates and other boron based compounds
• As a water coolant in nuclear reactors
• In electrolytic condensers and capacitors 1
