Part A.) Consider that you are titrating a diprotic weak base "B" which has pKb1=4 and pKb2=8. The product of the first ionization of B is BH+ and the product of the second ionization is BH22+. A 0.00500-mol sample of the base is dissolved in enough water to produce 100.0 mL of solution and is titrated with 0.500 M HCl. What is the exact pH when 7.2 mL of HCl is added? Enter your answer to three significant figures. Part...
