An analytical chemist is titrating

O ADVANCED MATERIALCalculating the pH of a weak base titrated with a strong acidAn analytical chemist is titrating 85.9 ml of a 0.2100 M solution of aniline (C H, NH, ) with a 0.07300 M solution of HNO?. The p K, of aniline is 9.37.Calculate the pH of the base solution after the chemist has added 99.3 ml of the HNO, solution to it.Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO, solution added.Round your answer to 2 decimal places.PH =X5?
