Making and Naming Acids Chemical formulation 4

Objectives Practice naming compounds with some common ion groups Calculate the names and formula for acids

Naming Acids The formulas of ALL acids begin with H (hydrogen). HNO3 H2S HBrO3

Naming Acids The names of ALL acids end with the word “acid.” Phosphorous acid Nitric acid Hydrochloric acid

NO OXYGEN HCl Hydrogen chloride Hydrochloric acid

NO OXYGEN OXYGEN GROUPS

Formula to name 1. Add the word acid to the end 2. Find the name of the ion group. 3.         Change “ate” → “ic” “ite” → “ous.” Name the compounds H2SO3: ____________ acid SO42- = sulphate SO32- Sulfite acid. Sulfous acid.

Name to formula Phosphoric acid: 1 Change “ic” → “ate” “ous” → “ite” 2         Find the charge of the ion group. 3 Add hydrogen and Balance the charges Phosphoric acid: Phosphoric -- phosphate phosphate = PO43- H+ PO43- H3PO4

That’s the end of chemical formulation!
