5. nomenclature Quiz
There will be a nomenclature Quiz Tuesday.

6. NAMING ACIDS
Acids are substances which give H+ ions when put in water.
If you see a compound that starts with an H, chances are it is an acid.
Two common exceptions are H2O and H2O2.

7. RULES FOR NAMING ACIDS
If the suffix of the anion is “-ide”, the acid compound starts with “hydro-“ and ends with “-ic”. Example: HBr ion is bromide hydrobromic acid

8. PRACTICE HF

9. RULES FOR NAMING ACIDS
If the suffix of the anion is “ate”, the acid compound ends in “ic” acid. Example: H2CO3 ion is carbonate carbonic acid

10. PRACTICE
HClO3

11. RULES FOR NAMING ACIDS
If the suffix of the anion is “ite”, the acid compound ends in “ous” acid. Example: HNO2 ion is nitrite nitrous acid

12. PRACTICE
HClO2

13. PRACTICE
1. HNO2
2. H2SO4
3. HC2H3O2
4. HCl
5. HI
6. HCN

14. Comes from carbonate, CO3-2
WRITING ACID FORMULAS
Look at the end of the acid name. If the acid ends in “-ic” and does not start with “hydro-”, then the anion ends in “-ate”.
Example:
Carbonic acid
Comes from carbonate, CO3-2
H+ and CO3-2 becomes H2CO3

15. PRACTICE
Dichromic acid

16. WRITING ACID FORMULAS
Look at the name. If the acid ends in “-ous”, then the ion ends in “-ite”.
Example:
Nitrous acid
Ion is nitrite, NO2-1
H+ and NO2-1 becomes HNO2

17. PRACTICE
Hypochlorous acid

18. WRITING ACID FORMULAS
Look at the name. If the acid ends in “-ic” and starts with “hydro-”, then the anion ends in “-ide”.
Example:
Hydrobromic acid
Ion is bromide, Br-1
H+ and Br- becomes HBr

19. PRACTICE
Hydrofluoric acid

20. PRACTICE Nitric acid Sulfurous acid Phosphoric acid Chromic acid
Hydrobromic acid
Hydrosulfuric acid

21. TO DO
