The pH of a solution is 10. Which of the following correctly describes the relative amounts of H+ and OH- in the solution? A. The amount of H+ is equal to the amount of OH- B. There is a high concentration of H+ and a low concentration of OH- C. There is a low concentration of H+ and a high concentration of OH- D. the pH only tells us about H+; it tells us noting about the amount of OH-
