At 25 °C for pure water Kw = [H+] [OH-] = 10-14M^2. a. Calculate Kc = [H+] [OH-]/[H2O], and Ka with activity defined relative to the Henry's law standard state. b. Use each of the Kc and Ka to calculate ?Gr of the water dissociation reaction H2O (l) --> H+(aq) + OH-(aq). What are the standard states for the three species in the two cases? Density of water is 997 kg/m^3.
