If one solution has an H₃O⁺ concentration that is 10 times less than that of another solution, the difference in pH is 10 units.

Question

Quizplus · Accepted Answer

The difference in concentration of 10 times would correspond to a difference in pH of 1 unit, not 10 units. The relationship between concentration and pH is not linear but logarithmic, with each unit difference in pH representing a 10-fold difference in concentration. Therefore, the correct statement would be that a 10-fold difference in concentration corresponds to a pH difference of 1 unit.
