Acid Base Calculations

What is the pH of a solution that has a [H+] of 2.5 x 10

^-5?

• 4.60

• 2.5

• 5.0

• 7

What is the [OH-] if the [H+] is 1.0 x 10^-3M?

• 1.0 x 10^-3 M

• 1.0 x 10^-14 M

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

• Base

• Salt

• Acid

• Water

A process used to find the molarity of an acid or base solution.

• molarity

• titration

• 1.0 x 10^-14

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

• 11

• -3

• 3

• 1

If the pH of a solution is 8 the [H₃O⁺] is

• 1.0 x 10⁶ M

• 8.0 x 10¹ M
