WebDiborane contains two bridging hydrogen atoms between two boron atoms; these bridge bonds are considered to be three-centre two-electron bonds. The important compounds of boron with dioxygen are boric acid and borax. Boric acid, B (OH) 3 is a weak monobasic acid; it acts as a Lewis acid by accepting electrons from hydroxyl ion. WebJun 19, 2024 · Boron is produced on a large scale by reacting borax with acid to produce boric acid [B (OH) 3 ], which is then dehydrated to the oxide (B 2 O 3 ). Reduction of the oxide with magnesium or sodium gives amorphous boron that is only about 95% pure: Na2B4O5(OH)4 ⋅ 8H2O(s)acid → B(OH)3(s) Δ → B2O3(s) B2O3(s) + 3Mg(s) Δ → 2B(s) …
