The hydrogensulfate ion (HSO − 4), also called the bisulfate ion, is the conjugate base of sulfuric acid (H 2 SO 4). [59] [b] Sulfuric acid is classified as a strong acid; in aqueous solutions it ionizes completely to form hydronium (H 3 O +) and hydrogensulfate (HSO − 4) ions.
Gallium(III) sulfate refers to the chemical compound, a salt, with the formula Ga 2 (SO 4) 3, or its hydrates Ga 2 (SO 4) 3 ·xH 2 O. Gallium metal dissolves in sulfuric acid to form solutions containing [Ga(OH 2) 6] 3+ and SO 4 2− ions.
The borosulfates are heteropoly anion compounds which have sulfate groups attached to boron atoms. Other possible terms are sulfatoborates or boron-sulfur oxides. The ratio of sulfate to borate reflects the degree of condensation.
Recently a machine translation of the Spanish article (which *looks* to be quite comprehensive) was attempted by the Spanish article's primary author User:Saeta (a.k.a es:Usuario:Lobillo) who clearly wants to expand the article and would surely be a great resource.

Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".
