2. The reaction Fe3+ (aq) + SCN (aq) → FeSCN2+ (aq) produces a dark red color...
My question is #2 for the reaction Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq). The goal is to predict the color change (darker or lighter) for test tubes 2-8. I have attached the supplemental sheets given to help with the problem. The test tubes 2-8 are being manipulated either by temperature or things being added which can be seen by one of the pictures. 2. For reaction "UCTIONS are increased by the same amount. Fe3+ (aq) + SCN (aq) $...
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,...
