A student mixes 5.0 mL 2.00 x 10-3 M Fe(NO3)3 with 4.0 mL 2.00 x l0-3 M KSCN, and 1.0mL deionized water. She finds that in the equilibrium mixture the concentration of FeSCN2+ is 1.2 x l0-4 M. Find Kc for the reaction Fe3+ (aq) + SCN-(aq) ↔ FeSCN2+(aq).
Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere.
