A. Using thermodynamics, calculate the equilibrium constant K at 25°C (The AG° of formation of
Fe(OH)3(s) is -699 kJ/mol).
B. Using the value of K you calculated in part a, if a solution contains 10-4 M Fe3+ and has a pH of 7.5,
will Fe(OH)3(s) precipitate? Show all calculations necessary to justify your answer. Note that the
reaction as written is for precipitation, not dissolution like Ksp-
