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

The lower the pH, the greater the concentration of :

• OH-
• H+

The greater the pOH, the smaller the concentration of 

• OH-
• H+

This indicates an acidic substance:

• [H⁺]<[OH^-]
• [H⁺]>[OH^-]
• [H⁺]:[OH^-]
