Question
When you cool down water to 10°C, Kw = 2.9 x 10-15, as compared to the value of
Kw at 25°C which is 1 x 10-14 (a bigger K at a higher temp). Which statement is true?
a) Dissociation of H₂O is endothermic; the pH of neutral water at 10°C is 14.5
b) Dissociation of H₂O is exothermic; the pH of neutral water at 10°C is 14.5
c) Dissociation of H₂O is endothermic; the pH of neutral water at 10°C is 7.27
d) Dissociation of H₂O is exothermic; the pH of neutral water at 10°C is 7.27
e) Dissociation of H₂O is endothermic; the pH of neutral water at 10°C is 7
f) Dissociation of H₂O is exothermic; the pH of neutral water at 10°C is 7
