1. Acids and Bases

2. 1. pH is a measure of how acidic or alkaline a liquid is on a scale of 0-14
Neutral 7
8-14 is a base
(Alkaline)
0-6 is an acid

3. 2. Acids are compounds that form H+ ions in a solution
a. Example: HCl  forms H+ ions in water
b. Turns litmus paper red
c. Corrosive and tastes sour
What are some real life examples?
lemon juice, orange juice

4. 3. Alkali (bases) are any compound that forms OH- ions in water
a. Example: NaOH  forms OH- ions in water
b. Turns litmus paper blue
c. Corrosive
What are some real life examples?
ammonia, oven cleaner, drain cleaner

7. 4. Buffers are weak acids or bases that help neutralize a strong acid or base
A. Acids and bases neutralize each other
B. the human body will buffer blood to keep the pH between 6.8 and 7.5.
Real life examples:
