In a sample of pure water, which of the following is NOT true?*1 point[H+] = [OH-][H+] = 1 x 10^-7 MpH = 7All of the above are true
Question
Solution 1
All of the above are true. In a sample of pure water:
[H+] = [OH-]: This is true because water self-ionizes into equal amounts of H+ and OH- ions.
[H+] = 1 x 10^-7 M: This is also true. In pure water at 25 degrees Celsius, the concentration of H+ ions is 1 x 10^-7 moles per liter.
