A solution with a pH of 10 is mixed with a solution with a pH of 4.  What would the pH of the mixture most likely be?

• 10

• 4

• 40

• 7

The pH scale is a range from:

• 1-7

• 0-14

• 1-14

• 1-20

A solution has a pH of 8. Is the solution acidic, neutral, or basic?

• Acidic

• Neutral

• Basic

• Cannot be determined

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

• Acid

• Base

• Neutral

• Acid and Base

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

• Base

• Acid

• Buffer

• Water

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
