Some compounds containing hydrogen are members of an important class of substances known as acids. The chemistry of these compounds is explored in more detail in later chapters of this text, but for now, it will suffice to note that many acids release hydrogen ions, H+, when dissolved in water. To denote this distinct chemical property, a mixture of water with an acid is given a name derived from the compound’s name. If the compound is a binary acid (comprised of hydrogen and one other nonmetallic element):
For example, when the gas HCl (hydrogen chloride) is dissolved in water, the solution is called hydrochloric acid. Several other examples of this nomenclature are shown in Table 1
Name of Gas | Name of Acid |
---|---|
HF(g), hydrogen fluoride | HF(aq), hydrofluoric acid |
HCl(g), hydrogen chloride | HCl(aq), hydrochloric acid |
HBr(g), hydrogen bromide | HBr(aq), hydrobromic acid |
HI(g), hydrogen iodide | HI(aq), hydroiodic acid |
H2S(g), hydrogen sulfide | H2S(aq), hydrosulfuric acid |
