Naming of Acids

Binary acids and Oxy-acids

Naming Binary Acids

• a binary acid is one with a hydrogen ion and a monatomic anion

• Binary acids are named by using the prefix "hydro-" followed by the root of the element/ion and then tagging on the suffix -ic

• All acids end with the word "acid"

• Examples: HCl = hydrochloric acid

• HBr = hydrobromic acid

• H₂S = hydrosulfuric acid
