QUESTION 9 Ionic Equilibria, pH, Indicators, & Buffers In Part C of this lab, the pH values of dilute solutions of acetic acid (HC2H302) of various concentrations are measured using a pH meter. These pH values are then used to calculate the equilibrium constant, K, for each solution. If the given concentration of an acetic acid solution is 0.010 M, and the pH is measured to be 3.35, what is Percent lonization () of the acetic acid?
