For simplicity, the acids that we will be concerned with naming are really just a special class of ionic compounds where the cation is always H+. So if the formula has hydrogen written first, then this usually indicates that the hydrogen is an H +^ cation and that the compound is an acid. When dissolved in water, acids produce H+^ ions (also called protons, since removing the single electron from a neutral hydrogen atom leaves behind one proton).
Since all these acids have the same cation, H+, we don't need to name the cation. The acid name comes from the root name of the anion name.
The prefix hydro- and the suffix -ic are then added to the root name of the anion.
All acids beginning with the prefix „hydro“ are otherwise known as binary acids.
Since all these acids have the same cation, H+, we don't need to name the cation. The acid name comes from the root name of the oxyanion name or the central element of the oxyanion. Suffixes are used based on the ending of the original name of the oxyanion. If the name of the polyatomic anion ended with -ate, change it to -ic for the acid and if it ended with -ite, change it to -ous in the acid.
