Naming Acids For those of us who didn’t know. Nia Gilliam 5/6 periods Chem. II tutorial
The Rules- for naming acids (#1) 1)If the anion doesn’t have an oxygen, use the prefix hydro-, the suffix –ic (even though it’s being phased out), and attach those to the root name for the element. Ex.) HCl (hydrogen chloride) is dissolved in water, it forms hydrochloric acid.
The Rules- for naming acids (#2) 2)If the anion does have an oxygen, the acid is formed from the root name of the central element of the anion or the anion name, and you would use a suffix of –ic or –ous. If the anion name ends in –ate, the suffix –ic is used. Ex.) H 2 SO 4 has the sulfate anion and is named sulfuric acid. If an anion has the –ite ending, we use the suffix –ous. Ex.) H 2 SO 3, which has sulfite, is named sulfurous acid.
