Consider the following system at equilibrium: Fes (s) = Fe²+ (aq) + S²- (aq) How would the concentrations of Fe2+ and S2- change to reestablish the equilibrium if potassium sulfide, K2S, was added to the system? Fe2* would increase, while s2 decreases. Os2- would increase, while Fe2* decreases. No change in Fe2+, but s2 would decrease The concentration of Fe2* and S2- would remain constant. O Fe2+ would increase, but S2 will not change.
