The answer 1.225 x 10^-7 is coming up as incorrect.
INTERACTIVE EXAMPLE Autoionization of Water The value of Ky at 25 °C is 1.0 x 10-14 At 30 °C, the value of Ky is 1.5*10-14. a.) Using LeChatelier's principle, predict whether the autoionization of water is exothermic or endothermic. 2 H2O(1) = H30+ (aq) + OH- (aq) b.) Calculate [H30*] and [OH-] in a neutral solution at 30°C. HOW DO WE GET THERE? What are the concentrations of [H3O+] and...

4. For the autoionization of water: 2 H2O(l) <=> H30+(aq) + OH*(aq) the equilibrium constant Kw is 1. 139 x 10-15 at 273.15 K and 9.614 x 10-14 at 333.15 K. Assume that AH° and ASº for this process are independent of temperature from 273 to 333 K. a) Determine AH° and ASº for the autoionization process. b) If the pH of pure water were 7.000 this would imply that Kw...
