Aqueous solutions of iron(III) chloride and sodium hydroxide are mixed together to form a combined solution that is 0.015 M FeCl3 and 0.010 M NaOH.
A)Calculate whether a precipitae forms in this solution, if so, what will be the precipitate ?
B) Would the precipitation status we determined in part A) remain the same if the solution also contains 0.10 M KCN ? Show quantitative proof for your answer.
The mixture did not rotate the plane of polarized light before. How had the mold changed the solution to become optically active?
