Problem- Two students performing the general unknown lab were told that their unknown would contain 4 cations. They first tested for the silver and aluminum, but found that another ion was present.
The students were conflicted about whether their unknown contained the iron cation because they did not observe precipitate when they added ammonium chloride and ammonia to make the solution alkaline. What suggestion(s) would you give these students to determine if iron (III) is present in their unknowns?
