Abstract Due to the addition of organic solvents to the mixture of phenol and ferric chloride solution,the color of water layer would change.Through dropper experiment,this paper verified that the reaction of phenol and ferric chloride solution showed different colors because of the solubility differences of phenol in different organic solvents,at the same time,through color change of the mixture,the solubility of phenol in different organic solvents could be qualitatively judged.
