Structure of orthoboric acid — Structure contains BOs3- units. In the solid the B(
OH)3 units are hydrogen bonded together into two dimensional sheets with
almost hexagonal symmetry. The layers are quite a large dis- o tance apart i.e.,
nearly ...
2-9-9 Boric Acid/Ortho boric acid Orthoboric acid is formed when the boron
halides are hydrolysed or when dilute hydrochloric acid is added to a solution of
borax. Na2B4O7 + 2HCI + 5H,O □* 4H,BO3 + 2NaCI It can also be obtained by
the ...

Boron trioxide in an acidic oxide and slowly reacts with water, forming orthoboric
acid. When fused with metallic oxides it forms borate glasses which are often
coloured; this is the basis of the borax bead test in qualitative analysis. Orthoboric

Dictionary of Environmentally Important Chemicals
Boron(III) oxide and orthoboric acid are highly toxic substances with multiple sites
of reaction. In particular, they display hepatotoxic and gonadotropic activity and
can be embryotoxic by virtue of being able to pass through the placental barrier.
