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.
