Acid Nomenclature. Binary Acids (H + element). Use the prefix “hydro” Use the root of the anion ( chlor , fluor , etc.) Add the suffix “ ic ” Put it all together and add the word acid Let’s try it for HF Hydro Fluor Ic Hydrofluoric Acid. Ternary Acids with –ITE (H + ion- ite ).

Binary Acids (H + element) • Use the prefix “hydro” • Use the root of the anion (chlor, fluor, etc.) • Add the suffix “ic” • Put it all together and add the word acid Let’s try it for HF • Hydro • Fluor • Ic • Hydrofluoric Acid
Ternary Acids with –ITE (H + ion-ite) • Identify the polyatomic ion • Change the suffex “ite” to “ous” • Add the word acid Let’s try it for HNO2 • The polyatomic ion is NO2 – Nitrite • Nitrite becomes Nitrous • Nitrous Acid
Ternary Acids with –ATE (H + ion-ate) • Identify the polyatomic ion • Change the suffex “ate” to “ic” • Add the word acid Let’s try it for HNO3 • The polyatomic ion is NO3 – Nitrate • Nitrate becomes Nitric • Nitric Acid
HCl Hydrochloric Acid
HClO2 Chlorous Acid
HClO3 Chloric Acid
Sulfurous Acid H2SO3
Sulfuric Acid H2SO4
