Problem Set in Precipitation, Acid-Base and Complexometric Titration 1. Consider a solution containing 10.0 mL 0.10 M Naf titrated with 0.01M TH(NO3)4. Calculate the pTh4+ with the addition of 1.0 ml, 25.0 ml, and 30.0 mL of the titrant. Ksp = 5.0x10-29 2. Consider a solution containing 100 mL of 0.04814 M HCOONa (sodium formate) titrated with 0.1831 M HCI. Calculate the pH of the solution with the addition of 0.0 20.0 mL, 31.0 and at the equivalence point. Ka = 1.7985x10-4 Kb = 5.56x 10-11 3. Consider titration of 50.0 mL of 0.0450 M malonic acid (diprotic acid) with 0.0978 M NaOH. Calculate the pH of the solution upon the addition of the following volumes of titrant: 19.3 ml, 23.0 mL, 37.5 mL, and 46.0 mL. Kal = 1.42 x 10-3 Ka2 = 2.01 x 10-6
