Chapter 7, Problem 7-E(choose chapter or problem)
A 40.0-mL solution of 0.040 0 M Hg2(NO3)2 was titrated with 60.0 mL of 0.100 M KI to precipitate Hg2I2 (Ksp 4.6 1029). (a) Show that 32.0 mL of KI are needed to reach the equivalence point. (b) When 60.0 mL of KI have been added, virtually all Hg2 2 has precipitated, along with 3.20 mmol of I. Considering all ions remaining in the solution, calculate the ionic strength when 60.0 mL of KI have been added. (c) Using activities, calculate for part (b). 7-F
