You have 100.0 mL of 0.100 M aqueous of each of the following acids: HCN, HF, HCl, and HC2H3O2. You titrate each with 0.100 M NaOH (aq). Rank the pHs of each of the solutions when each are titrated at the equilibrium point, from highest to lowest pH.
Ka for HCN = 6.2 10^-10
Ka fpr HF = 7.7 10^-4
Ka for ?HC2H3O2 = 1.8 10^-5
