Question: A solution is made by mixing 100mL Fe 3+ solution of 1.00 x 10 -3 M and 100 mL A - ion solution of 1.00
A solution is made by mixing 100mL Fe 3+ solution of 1.00 x 10 -3 M and 100 mL A - ion solution of 1.00 x 10 -3 M. The mixture has a deep blue color, indicating the formation of a complex between Fe 3+ and A - . By a spectrophotometric analysis, we find that 30.0% of Fe 3+ is in the form of the complex and there are two probable products which are FeX 2+ or FeX 3
Balance the following equations and calculate the concentrations of the remaining species
(i) Fe 3+ + A - <--> FeA 2+
(ii) Fe 3+ + A - <--> FeA 3
Assuming that the final state reached equilibrium, write the equilibrium expressions and calculate the equilibrium constants for both cases in (a)
