Which of the following solutions would have the highest pH?  Assume that they are all 0.10 M in acid at 25oC   Chapter 17 & 18 equations: pH = -log[H3O+] pOH = -log[OH-] pH + pOH = 14.00 Kw = 1 x 10-14 Ka x Kb = Kw = [H3O+][OH-] pKa = -log Ka pH = pKa + log  

Determine the [H3O⁺] in a 0.265 M HClO solution.  The Ka of HClO is 2.9 × 10-8   Chapter 17 & 18 equations: pH = -log[H3O+] pOH = -log[OH-] pH + pOH = 14.00 Kw = 1 x 10-14 Ka x Kb = Kw = [H3O+][OH-] pKa = -log Ka pH = pKa + log
