Binary acids are certain molecular compounds in which hydrogen is combined with a second nonmetallic element.
Examples: CH4, NH3, H2O, HF, HCl, HBr, HI
Their strengths depend on the solvation of the initial acid, the H-X bond energy, the electron affinity energy of X, and the solvation energy of X. Observed trends in acidity correlate with bond energies, the weaker the H-X bond, the stronger the acid. For example, there is a weak bond between hydrogen and iodine in hydroiodic acid, making it a very strong acid.
Binary Acids are one of two classes of acids, the second being Hydroxy Acids, which consist of a hydrogen, oxygen, and some other element.
