PH Calculation

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

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

Which of the following pH values represents a base?

• 2.1

• 4.6

• 6.8

• 8.1

The strongest bases have pH values close to

• 0

• 14

• 7

• 5

If a solution has an [OH-] concentration of 1.0 x 10^-3 M then what is the pH ?

• 3

• -3

• 11

• -11

An acid has a pH of 4. What is the [OH-] concentration?

• 4 M

• 10 M

• 1 x 10^-4 M

• 1 x 10^-10 M

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

The pH of a solution is 7.880. What is the concentration of [H₂O⁺] in the solution?

• 5.86 x 10^-8 M

• 4.12 x 10^-8 M

• 1.32 x 10^-9 M

• 3.67 x 10^-8 M

• 1.32 x 10^-8 M
