The pH and pOH scales

- Measures the amount of H+ in a solution.
- Scale used to measure whether a substance is an acid or a base.
- Lower numbers are acids.
- Higher numbers are bases

- Which of the following pH values represents the strongest acid?
A) 12.0

B) 9.0

C) 2.0

D) 7.0

- Which of the following pH values represents the weakest base?
A) 12.0

B) 9.0

C) 2.0

D) 7.0

- Measures the amount of OH- in a solution.
- The pH and pOH scales are related by the following equation.
pH + pOH = 14

- Ex: What is the pOH of a solution if its pH is 4?
Is it an acid, base, or neutral?

- Ex: What is the pH of a solution if the pOH is 9?
Is it an acid, base, or neutral?
