(a) Calculate the pH of a solution prepared by mixing 1.00 g of imidazole with 1.00 g of imidazole hydrochloride and diluting to 110.5 mL. (FM of imidazole = 68.08. Ka for imidazole = 1.02 * 10-7.)
(b) Calculate the pH of the solution if 2.30 mL of 1.07 M HClO4 are added.
(c) How many milliliters of 1.07 M HClO4 should be added to 1.00 g of imidazole to give a pH of 6.993?
