Take-Home Assignment #4 Please turn in neatly worked solutions for the following problems. Answers are due by 4:00 PM on Wednesday, September 12 th . The intention of these problems is to provide experience in solving equilibrium problems. Equilibrium constants for all reactions may be found in the Appendices. Use ladder diagrams to help you simplify equilibrium problems. 1. Calculate the solubility of Zn 2 [Fe(CN) 6 ] in (a) distilled water, and (b) in 0.00010 M K 4 Fe(CN) 6 . 2. Write a charge balance equation for a solution containing (NH 4 ) 3 PO 4 . Be sure to consider all possible equilibrium reactions.
