pH Calculations

The pH scale is a range from:

• 1-7
• 0-14
• 1-5
• 1-20

A(n) ______ is a substance with a pH less than 7

• Acid
• Alkaline
• Base
• Buffer

What is the only substance with a neutral pH of 7?

• Milk
• Orange Juice
• Water
• Blood

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

A  pH and a pOH will add up to:

• 0
• 7
• 14
• 1.0 x 10^-14

A solution with a [H+] of 9.4 x 10^-5 mol/L is said to be

• Acidic
• Basic
• Neutral
• negative number, no solution.

Limes have a [H₃O⁺] of 1.3 x 10^-2 mol/L.  Their pOH is

• 1.89
• 12.11
• 1.03
• 12.97

A(n) _______ is a substance with a pH greater than 7.

• Base
• Acid
• Buffer
• Water

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

• 10
