Borates result either from the reaction of a base with a boron oxyacid or from the melting of boric acid or boron oxide, B2O3, with a molten metal oxide or hydroxide. |
The electronic structure of hypophosphorous acid is such that it has only one hydrogen atom bound to oxygen, and it is thus a monoprotic oxyacid. |
Just as certain elements form more than one oxyanion, they also form more than one oxyacid. |
