Boron trifluoride reacts with water to give boric acid and fluoroboric acid. Boric acid is soluble in boiling water. The simplest hydroxide of boron B(OH), known as boric acid, is an acid. They are produced by treating boric acid or boron oxides with metal oxides. At neutral pH boric acid undergoes condensation reactions to form polymeric oxyanions. Roach attractants are mixed with the boric acid. All borates can be considered derivatives of boric acid, B(OH). The halides react with water to form boric acid. Boric acid and its salts are found in seawater. Mild solutions of boric acid have been used as eye antiseptics. A weak acid like boric acid (HBO) in excess of ammonia is often used. Mannitol can be used to form a complex with boric acid. In his subsequent experiments, he used potassium to reduce boric acid instead of electrolysis. Boric acid powder is mostly used for this purpose. Then, he dusted the surface with iodoform and boric acid powder.
