1. Making and Naming Acids
Chemical formulation 4

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

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

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

5. NO OXYGEN
HCl
Hydrogen chloride
Hydrochloric acid

6. NO OXYGEN
OXYGEN GROUPS

7. Formula to name 1. Add the word acid to the end
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.

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

9. That’s the end of chemical formulation!
