Phenol and fecl3

The sample is dissolved in water, or a mixture of water and ethanol, and a few drops of neutral ferric chloride (FeCl3) solution, which is prepared by adding de-ionised water. Add sodium hydroxide to the mixture until a permanent brown precipitate is formed. The formation of a red, blue, green, or purple coloration indicates the presence of phenols. Where the sample is insoluble in water, it may be dissolved in dichloromethane with a small amount of pyridine. WebFeCl3 is used to indicate the presence of a phenol group by producing a purple color. In this experiment, the crystalline product turned colored as a result of still having salicylic acid present because it contains a phenol group. It can be a result of improper heating.
