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
