Main relationships between pH, pOH, [H+] and [OH-] at 25◦C
The table on the right lists values of the ionic product of water Kw at different temperature and the corresponding pH for pure water. While the value of Kw is constant at a given temperature, it increases when temperature increases.
Note that since [H+]=[OH-] in pure water, the pH of pure water varies with temperature. |
