How does a change of one unit in pH affect the hydrogen ion concentration [H+]?

Options

  1. AA change of one unit in pH has no effect on [H+].
  2. BA change of one unit in pH increases [H+] by a factor of 100.
  3. CA change of one unit in pH decreases [H+] by a factor of 10.
  4. DA change of one unit in pH increases [H+] by a factor of 10.

Correct answer

D. A change of one unit in pH increases [H+] by a factor of 10.

Step-by-step solution

The pH scale is logarithmic, and a change of one unit in pH corresponds to a factor of 10 change in [H+].
