Use a systematic treatment of equilibrium to calculate the pH of a solution prepared by diluting 0.467 g of aniline (aminobenzene, C6H5NH2) to 100.0 mL. Pertinent equilibria include the dissociation of the weak base and the autoprotolysis of water. a. Write out the mass balance and charge balance equations. b. Write the associated equations for the equilibrium constants for the pertinent equilibria. c. Make the assumption that [BH+] ~[OH-] and solve for [OH-]. Calculate the pH of the solution. Verify that the assumption was justified. Calculate the fraction of dissociation a.
