Acids

Acids are compounds that give off hydrogen ions, (H + ) when dissolved in water. When a compound has hydrogen as its cation the substance is generally an acid –Examples: HCl, H 2 SO 4, H 3 PO 3 The rules for naming acids are based on the anion portion of the acid formula.

Rules for Naming Acids The names of acids are based on the ending of the anion name. –Examples: HCl, H 2 SO 4, H 3 PO 3

Rules for Naming Acids The names of acids are based on the ending of the anion name. –Examples: HCl, H 2 SO 4, H 3 PO 3 Cl‾ = chloride

Rules for Naming Acids The names of acids are based on the ending of the anion name. –Examples: HCl, H 2 SO 4, H 3 PO 3 Cl‾ = chloride SO 4 2 ‾ = sulfate

Rules for Naming Acids The names of acids are based on the ending of the anion name. –Examples: HCl, H 2 SO 4, H 3 PO 3 Cl‾ = chloride SO 4 2 ‾ = sulfate PO 3 3 ‾ = phophite
