1/ How would you separate Group III cations from Group I cations?
2/ To detect if Fe3+ is present in a sample, NH4SCN was
added.
a. What color would indicate the presence of Fe3+?
b. As long as their concentrations are large enough, Fe3+ and
NH4SCN will form a precipitate. Write the complete and balanced
equation for Fe3+ and NH4SCN for this reaction.
