If the pKa for acetic acid, found in commercial white vinegar is 4.754 at 298K, then calculate the pH, percent ionization, and pOH of a 0.585 M acetic acid of 5% vinegar solution. Do not forget to first determine the Ka, setup an "ICE" table, define the equilibrium concentrations of the finally and the significantly present at equilibrium.
