Questiоns 23-26 use the fоllоwing informаtion: 25.0mL of 0.110M HC2H3O2 is titrаted with 0.120M NаOH. Ka for HC2H3O2 is 1.8 x 10-5 Question 25: What is the pH of the solution when 11.5mL of NaOH is added to the HC2H3O2? Equations Chapters 17-18: pH = -log[H3O+] pOH = -log[OH-] pH + pOH = 14.00 Kw = 1 x 10-14 at 25oC Kw = Ka x Kb = [H3O+][OH-] pKa = -log Ka pH = pKa + log
