1. Acids and Bases Chapter 20

2. Properties of Acids Sour pH 1 to 6.9 Form electrolytes in water Turns Litmus red React with solid metals in aqueous solution to form hydrogen gas

3. Contains acid

4. Properties of Bases Slippery Bitter taste Forms electrolytes in water Turns litmus blue

5. Contains base

7. Naming Acids Binary acids : acids that are made of only two elements. Anion end in –ide. A. Prefix is always hydro B. Name the second element with the suffix; -ic acid Example: HCl is Hydrochloric acid

8. Naming Acids continued polyatomic anions. Anion ends in –ite - A. acid ends in –ous acid - Example: H 2 SO 3 is Sulfurous acid

9. Naming Acids concluded polyatomic anions. Anion ends in –ate - A. acid ends in –ic acid - Example: H 2 SO 4 is Sulfuric acid

10. Naming Bases To name a base, use the ionic compound nomenclature. Example: KOH, NaOH Potassium hydroxide and sodium hydroxide

11. Safety in the Lab Do what you oughter, Add acid to water. teacher_had_a_science_acciden t_hg_clr.gif (Right click on the image to download)

12. Safety continued. Adding water to acid will cause it to heat and splatter. This will damage skin and eyes. Wash with water and soap!! dangerous_experiment_hg_wht.gif (Right click on the image to download)

13. Safety Continued Due to the slippery nature of bases, They are more dangerous to your eyes than acid!! Wear your goggles!!
