1. Properties of Acids & Bases By: Ms. Bowie

2. Acids are substances that: Taste sour!

3. Property #2 Acids turns blue litmus paper red! Drop of acid on the litmus paper!

4. Property #3 An acid will NEUTRALIZE a base. That means that the pH of the base will drop down to around pH 7. H + + OH - H 2 O

5. Property #4 Acids conduct ELECTRICITY. ACID

6. Property #5 Acids react with active metals to produce hydrogen gas. HCl + Zn ZnCl + H 2 Note that precious metals like gold and platinum are not ACTIVE and do not react with acids.

7. Property #6 Acids react with carbonates to produce CARBON DIOXIDE GAS. HCl + baking soda CO 2 + …. (sodium bicarbonate ).

8. Properties of Bases

9. Bases are substances that: Taste bitter!

10. Property #2 Bases feel slippery! Or “Soapy”

11. Property #3 Bases turns red litmus paper blue! Drop of base on the litmus paper!

12. Property #4 A base will NEUTRALIZE an acid. That means that the pH of the acid will rise to around pH 7. H + + OH - H 2 O

13. Property #5 Bases also conduct ELECTRICITY. BASE

14. That’s All Folks!
