1. Acids and Bases
Pop Can Acids and Bases

2. What is an acid? Tastes sour pH less than 7
Turns blue litmus paper red
Neutralizes bases and produces salt

3. What is a base? Tastes bitter and feels slippery
Turns red litmus paper blue

4. Salts Acid + Base = Salt + Water
Salt DOES NOT always mean the salt we think of.

5. pH: concentration of Hydrogen ions
More hydrogen ions = Acids Less hydrogen ions = Bases
