The pH scale is a range from:

• 1-7
• 0-14
• 1-14
• 1-20

What does pH measure?

• Amount of Oxygen Ions
• Amount of Hydrogen/Hydronium Ions
• The amount of salt in a solution
• The density

What is the [H+] if the pH is 4.0?

• 1.0 x 10-10  M
• 1.0 x 10-4  M
• 1.0 x 10-14  M
• 1.0 x 10-7  M

What is the pOH of a solution that has a pH of 2?

• 10
• 12
• 14
• 1

The lower the pH, the greater the concentration of :

• OH-
• H+

The greater the pOH, the smaller the concentration of 

• OH-
• H+
