Question and answer
Q: What is the pH of a [H30+]=0.2 M solution? A. pH = 0.2 B. pH = 0.7 C. pH = 1.7 D. pH = 2.2
A: In a solution, hydrogen ions normally bond with molecules of water, forming H3O+ (hydronium) ions. [ Thus, the concentration of the hydronium ions will be the same as the concentration of hydrogen ions, which is related to the pH of a solution according to the following equation: pH = -log[H+] = -log[H3O+] This equation can be solved for the concentration of hydronium ions: [H3O+] =
10-pH Thus, for a solution with a pH of 3, the concentration of hydronium ions will be 10-3 = 0.001 moles/liter ]
