Absolutely not.
At that temperature (H^+) = (OH^-). At 50 C, pH = 6.63, pOH = 6.63. So what's the catch? The catch is that pKw is not 14 but rather 6.63+ 6.63 = 13.26 and Kw is not 1E-14 but 5.49E-14.
If a neutral solution of water, with pH = 7.00, is heated to 50 deg C , the pH drops to 6.63.
Does this mean that the concentration of [H+] is greater than the concentration [OH-]of ?
