Ocean Acidification

pH measures

• The mass

• The hydrogen ion concentration in a substance

• The concentration of nitrogen in a substance

• The concentration of oxygen in a solution

The pH scale ranges from

• 0 to 14

• 0 to 7

• 0 to 5

• 0 to 28

On the pH scale, anything below 7.0 is

• acidic

• alkaline

• basic

On the pH scale, anything above 7.0 is

• alkaline

  or basic

• acidic

Pure water has a pH value of exactly

• 7

• 8

• 5

• 14
