To determine whether a color change can be expected when FeCl3 is added to pure aspirin and oil of wintergreen, we need to consider the chemical reactions that can occur.
For pure aspirin, which is mainly composed of salicylic acid, FeCl3 can react with the phenolic -OH group in salicylic acid to form a colored complex called iron(III) salicylate. This complex often appears purple or violet. Therefore, if FeCl3 is added to pure aspirin, a color change to purple or violet can be expected.
As for oil of wintergreen, it primarily contains methyl salicylate, which is a derivative of salicylic acid. However, the other compounds present can vary depending on the source and method of extraction. Assuming that oil of wintergreen contains methyl salicylate and potentially some impurities like methyl acetate, we can focus on the main component.
Similar to pure aspirin, FeCl3 can react with the phenolic -OH group in methyl salicylate to form an iron(III) salicylate complex. Therefore, a similar color change to purple or violet can be expected when FeCl3 is added to oil of wintergreen.
