The relationship between [H+] and [OH-] is connected by the following equation:
Kw = autoionization constant of water
Kw = 0.12×10-14 at T = 0°C
A neutral solution has [H+] = [OH-]. Denoting these concentrations as x, we can determine the concentrations of these ions:
x = [H3O+] = 3.46×10-8
The Kw for water at 0 C is 0.12 x 10^-14 . Calculate the pH of a neutral aqueous solution at 0°C?
