11. Acids vs. Bases Properties
Tastes sour
Feel rough
Reacts vigorously with metals to produce H2 gas
Indicators
Turn blue litmus paper red
Phenolphthalein is colorless
Bases
Tastes bitter
Feel slippery
Do not react with metals
Indicators
Turn red litmus paper blue
Phenolphthalein is purple/pink

12. Similarities between Acids and Bases
When dissolved in water, they are both electrolytes and create an electrical current
Acids neutralize bases to produce salt and water

13. Complete the activity to construct a set of rules for naming acids
NAMING ACIDS ACTIVITY
Complete the activity to construct a set of rules for naming acids

14. NAMING ACIDS NOTES

15. Naming Acids
The name usually comes from the anion

16. Naming Acids
If the anion ends in –ide, the prefix begins with hydro- and the suffix changes to –ic
Example: HCl
Hydrogen chloride becomes Hydrochloric acid
Example: HBr = Hydrobromic acid
These are binary acids

17. Naming Acids
Other acids take the name of their anion without the prefix hydro-
The suffixes also change as follows
–ate  -ic
HNO3 = nitric acid
H3PO4 = phosphoric acid
–ite  -ous
H3PO3 = Phosphorous acid
