1. pH
The Power of Hydrogen

2. II. What is pH? A. Acids = range B. Neutral = pH = C. Bases = range =
1. Ions present
B. Neutral = pH =
1. ions present
C. Bases = range =

3. II. What is pH? A. Acids = 0-6 B. Neutral = 7 C. Bases = 8-14
More H+ ions
B. Neutral = 7
-equal # of H+ and OH- ions
C. Bases = 8-14
More OH- ions

4. D. What is the pH scale?
Bases are often soapy substances

5. pH = The Power of H+
The more acidic the solution the greater the concentration of H+ ions

6. The more basic (alkaline) a solution the greater the concentration of –OH ions

7. Practice Fill out your chart now!
Color your pH scale to show the acidic, basic and neutral parts.
The strongest acids and bases are on the end.
Use shading to show the strength of the acid and bases increasing

8. After Coloring 1. Add the items listed in the table to the scale.
2. Label the arrows as “Acids getting stronger” or “Bases Getting Stronger”

9. Practice
A scientist measured the pH of four fluids in an organism. Which fluid is a strong acid? A) 13.4 B) 8.2 C) 7.0 D) 2.3
