If the water is pure, then the only ions are from the decomposition of H2O, which are H+ and OH-. These must be in equal numbers because each water molecule decomposes in one of each. Thus [H+] = [OH-] and since their product is the given value of Kw = 2.92 x 10^(-14), each is equal to the square root of this:
[H+] = [OH-] = 1.71 x 10^(-7).
From this follows the pH from its definition:
pH = - log base 10 of [H+] = 6.77
