The stock solution at equilibrium used in test tube #4 contains Fe 3+ (aq), SCN- (aq) and [FeSCN]2+ (aq). When NaOH was added to test tube #4 a shift in equilibrium was observed. What chemical species in the stock solution reacted with NaOH? Write the balanced chemical reaction associated with the change observed from the addition of NaOH to test tube #4?
