Iron thiocyanate (FeSCN2+) is a complex ion that appears orange-red in solution. Iron(III) (Fe3+) and thiocyanate (SCN-) are both colorless in solution. FeSCN2+ (aq) --(equilibrium)-- Fe3+ (aq) + SCN- (aq) a) If you add Fe(NO3)3 to a solution of these ions at equilibrium, in which direction will the reaction run to reach a new equilibrium? b) Silver ions react with thiocyanate ions to form a white precipitate. If you add silver ions to a solution of these ions at equilibrium,...

Laboratory 11, Equilibrium Control of a Reaction Name Chemical Equilibrlum: equilibrium is when the rates of the forward and reverse reactions are equal. Therefore, the concentration of all reactants and products remain constant. This is not to say that the reaction has ceased. It is a dynamic situation at chemical equilibrium with the rate of disappearance of reactants the same as the rate of appearance of reactants through the reverse reaction (the same for the rate of disappearance and appearance...
