Naming acids and bases

1. Naming acids and bases

2. Naming Binary Acids • Binary acids contain 2 elements • Steps to name: • Start with “hydro” • Name the element • Change the ending to “ic” • Add the word acid at the end

3. Binary Acid Example • Name HCl ic hydro chlorine acid hydrochloric acid

4. Name the following… • HF • HBr • H2S • Hydrofluoric acid • Hydrobromic acid • Hydrosulfuric acid Note: sulfur is an exception, because it sounds funny otherwise 

5. Oxyacids • Polyatomic ions that are acids • You will know it is an acid if it starts with an H

6. Remember these…Polyatomic Ions

7. Other Polyatomic Ions

8. Naming acids ending in -ate • If a polyatomic ends in –ate, drop the ending and add –ic to the end. • Write the word acid after. • Example: HC2H3O2 Acid Acetate ic Acetic Acid

9. Name these acids • H3PO4 • HNO3 • Phosphoric Acid • Nitric Acid Phosphoric Acid is another exception, because it sounds funny 

10. Naming acids ending in -ite • If a polyatomic ends in –ite, drop the ending and add –ous to the end. • Write the word acid after. • Example: HNO2 Acid ous Nitrite Nitrous Acid

11. Name these acids • H2SO3 • HClO2 • Sulfrous Acid • Chlorous Acid Remember: sulfur is an exception, because it sounds funny otherwise

12. Name these acids

13. To remember acid endings…think…I “ate” something “ic” ky

14. Naming Bases • Bases have –OH in them • Except Ammonia (NH3) • To name: • Name the metal • Add hydroxide at the end • Example: NaOH Sodium Hydroxide
