How does a change in [H+] by a factor of 100 affect the value of pH?

Options

  1. AA change in [H+] by a factor of 100 has no effect on pH.
  2. BA change in [H+] by a factor of 100 decreases the value of pH by 2 units.
  3. CA change in [H+] by a factor of 100 increases the value of pH by 2 units.
  4. DA change in [H+] by a factor of 100 decreases the value of pH by 1 unit.

Correct answer

C. A change in [H+] by a factor of 100 increases the value of pH by 2 units.

Step-by-step solution

When the hydrogen ion concentration [H+] changes by a factor of 100, the value of pH changes by 2 units.
