NAMING ACIDS NOTES

Chemistry

Naming Binary Acids

Binary acid: H + Element Naming Acid:

Name hydrogen using hydro- Use the root word of the element and

change ending to –ic acid

Examples H2S – hydrosulfuric acid HBr – hydrobromic acid

Naming Ternary Acids

Ternary Acid: H + Element + Element (polyatomic ion)

Naming Acid: do NOT use hydro- Use anion name and acid If anion ends in –ate, change it to –ic

acid If anion ends in –ite, change it to –ous

acid

Examples HClO3 (ClO3 = chlorate) chloric acid

HClO2 (ClO2 = chlorite) chlorous acid
