Question

Quizplus · Accepted Answer

The difference of pH by 1 unit means a difference of 10 in the concentration of hydronium ions (H3O+) and therefore the concentration of hydroxide ions (OH-) decreases by 10 times. Therefore, a solution with a pH of 2 has 10 times more H3O+ ions than a solution with a pH of 3, which also means it has 10 times more H⁺ ions.
