Part A the value of Ky at that temperature? Water ionizes by the equation H2O(l) = 1+ (aq) + OH-(aq) The extent of the reaction is small in pure water and dilute aqueous solutions. This reaction creates the following relationship between (H+) and (OH): Ky = [H+][OH-] Keep in mind that, like all equilibrium constants, the value of Kw changes with temperature. At a certain temperature, the pH of a neutral solution is 7.65. What Express your answer numerically using...
