At 50 C, the ion-product constant for H 2 O has the value K w = 5.48
Question:
At 50 °C, the ion-product constant for H2O has the value Kw = 5.48 x 10-14.
(a) What is the pH of pure water at 50 °C?
(b) Based on the change in Kw with temperature, predict whether ΔH is positive, negative, or zero for the autoionization reaction of water:
2H2O(l) ⇌ H3O+(aq) + OH-(aq)
