Benzoic acid (C6H5CO₂H) is a common organic acid. Consider a solution is prepared by dissolving 0.780 g of C6H5CO₂H (Ka = 6.4 x 10-5) in a total solution volume of 1.25 L. Using the information above, calculate: a. The pH of the solution. b. The concentrations of all species present in at equilibrium.
