Design a distillation column that can effectively separate a mixture containing 50 wt% methanol and 50 wt% water. The column should produce a distillate with no more than 5 wt% methanol and a bottom product with no more than 2 wt% water. The feed rate is 1000 kg/h and the column must operate at atmospheric pressure. Assume that the feed is a saturated liquid and that the methanol-water mixture behaves as an ideal solution. Provide the design specifications for the column, including the number of trays or packing height, diameter, and other necessary specifications.

What effect does a change in the concentration of ligands have on the formation of a complex ion in a solution of FeCl3? How does this affect the equilibrium constant of the reaction and what is the relationship between the concentration of the ligands and the stability constant of the complex ion? Calculate the equilibrium concentrations of the species involved and determine their values at different stages of the reaction. Use the given data and appropriate equations to solve the problem.
