All of the above are true. In a sample of pure water:

1. [H+] = [OH-]: This is true because water self-ionizes into equal amounts of H+ and OH- ions.

2. [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.

3. pH = 7: This is true as well. The pH of a solution is defined as the negative logarithm (base 10) of the H+ ion concentration. If the concentration of H+ ions is 1 x 10^-7 M, the pH is 7.

So, all of the above statements are true for a sample of pure water.
