Question

what is the color changes if FeCl3 added with pure aspirin?
Dr Russ
FeCl3 will not react with aspirin. It will, however, react with salicylic acid, which is used to synthesize aspirin. Thus by adding an aqueous FeCl3 solution to a sample of aspirin is a good way to see if there is any unreacted salicylic acid. A purple colour is an indication of salicylic acid. A sample of pure aspirin should not exhibit a colour change.
