with asprin, then there should be no reaction as there is no phenol group (-OH attached to a benzene ring) for the iron (III) chloride to react with. However, the phenol group is present in salicylic acid, so a brightly coloured violet-purple colour is seen. still trying to find out the reaction between S.A and the iron chloride though.

as to the last answerer (sp?), the aspirin should hydrolyse back to salicylic acid and acetic anhydride. however, acetic anhydride is so reactive, that the reaction will immediatly reverse again, or it will (more likely) convert back into its original substance acetic ethanoate on contact with water (even water from the air will allow this to happen)

hope that helps
