pH and pOH Calculations

If the pOH of a solution is 2, what is the pH of the solution?

• 2

• 12

• 14

• 7

Calculate the hydroxide ion concentration of a solution with a pOH of 3.

If the pOH of a solution is 11, what is the hydroxide ion concentration?

A solution has a pH of 7. Is the solution acidic, neutral, or basic?

• Acidic

• Neutral

• Basic

• Cannot be determined

For a solution, pH + pOH =

• 7

• 14

• 1.0 x 10^-14

• -log (1.0 x 10 ^-14)

If the pH of a solution is 4.0, what is the pOH?

• 4.0

• 10.0

• 1.0 x 10 ^-4

• cannot be determined from the information

If the [H₃O⁺] of a solution is 1 x 10^-3 M, the pH is

• 11

• -3

• 3

• 1

The pH of a solution is 9. What is the [H₃O⁺]concentration?

• 1 x 10 ^-9

• 1.0 x 10⁹

• 1 x 10^-5

• 1.0 x 10⁵

If a solution has a pOH of 4 the [OH-] of the solution is

• 5.0 x 10^-11 M

• 1.0 x 10^-4 M

• 10 M

• 14 M

If the pH of a solution is 5, what is the pOH of the solution?

• 9

• 5

• 14

• 7
