When an acid’s original anion ends in “-ide”, the “hydro-” prefix is added and the “-ic” suffix is adopted. Name these acids: HCl, HBr, HCN.
Hydroclauric acid, hydrobromic acid, and hydrocyanic acid.
When an acid’s original anion ends in “-ate”, the “-ic” suffix is adopted. Name these acids: HNO3, HClO4, H3PO4.
Nitric acid, perchloric acid, phosphoric acid.
When an acid’s original anion ends in “-ite”, the “-ous” suffix is adopted. Name these acids: HNO2, HClO.
Nitrous acid, hypochlourous acid.
Neutral acids have all of their hydrogen. Ex: H2SO4. Acids that have lost a hydrogen use “molecule” form to list the number of hydrogen present. Name these acids: H2PO2-, HSO4-.
Dihydrogen phosphate, hydrogen sulfate.
