Calculate the ratio of dissolved benzioc acid to benzoate ion that will exist in solution at equilibrim at a pH of 2.00. The acid equilibrim constant (k) for benzoic acid is 6.46 X 10 ^5. Note that this calculatio doesn't account for the benzoic acid that has precipitated from solution, but you can assume that the higher the ration, the more benzoic acid will precipitate. Carry out same calculation for a pH of 4.00 and explain why it was important to reduce the pH to below 4 in this expirement.
