Examples of binary acids include hydrofluoric acid, hydrochloric acid, hydrobromic acid and hydroiodic acid. A binary acid is a compound or a solution where one element is a nonmetal substance and the other element is hydrogen.
A binary compound or a binary solution is one that is comprised of two elements. A binary acid is a combination of two elements, one of which is an acidic nonmetal and the other element is hydrogen. Together these two elements create a binary acid, such as hydrosulphuric acid or hydroiodic acid. The strength of binary acids varies, and is dependent on the solvation of the acidic nonmetal in the compound. There are two classes of acids. One is binary acids, the other is oxoacids or oxiacids. Oxi acids, unlike binary acids, contain hydrogen, oxygen and an acidic element.
