PH Biology

A liquid with a pH of 4 is _x more concentrated in H⁺ than a liquid with a pH of 6. 

• 10
• 100
• 1,000
• 10,000

A solution with a pH of 8.6 would be...

• Acid
• Base
• Neutral
• Acid and Base

A solution with a pH of 3.6 would be...

• Acid
• Base
• Neutral
• Acid and Base

A solution with a pH of 7.0 would be...

• Acid

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+
