A solution with a pH of 5 has how many more protons in it than a solution with a pH of 7?

Question

Quizplus · Accepted Answer

The pH scale measures the concentration of hydrogen ions (H+) in a solution. The difference in pH between two solutions corresponds to a tenfold difference in H+ concentration. A solution with a pH of 5 has 100 times more H+ than a solution with a pH of 7 (since 7-5=2, and 10 raised to the power of 2 is 100). Therefore, the answer is C, 100 times more protons in the pH 5 solution.
