Distillation
One way to separate this mixture is through a process called liquid-liquid extraction. Aniline and benzoic acid are both water-soluble, while chloroform is not. By adding water to the mixture, the aniline and benzoic acid will dissolve in the water phase, leaving the chloroform to be separated out. The aniline and benzoic acid can then be recovered from the water phase by adjusting the pH of the solution.

Chloroform is immiscible in water, so you can separate chloroform extract from water using liquid-liquid extraction. By adding chloroform to the mixture, the two layers will separate based on their immiscibility. After shaking and allowing the layers to separate, the chloroform layer can be carefully decanted or extracted using a separatory funnel.
You can separate water from chloroform by utilizing their difference in density. Since chloroform is denser than water, the mixture can be placed in a separatory funnel. Upon standing, the two liquids will separate into distinct layers, allowing the water to be drained from the bottom.
Chloroform is a solvent that helps to separate the three phases in phenol-chloroform extraction by disrupting the interactions between the biomolecules. RNA, DNA, and proteins have different affinities for phenol, chloroform, and water, leading to their partitioning into separate phases based on their solubility. Chloroform enhances the separation by forming distinct layers that can be easily separated, allowing for the isolation of the desired biomolecules.

At 20o C aniline's rate of solubility in water is 3.6g/mL. So, aniline mixes with water unlike kerosene which forms a layer above the water. Separating funnel is used to separate two immiscible liquids and cannot separate miscible liquids. Hence, we cannot separate water and aniline using separating funnel.

Chlorine from a pool cannot turn directly into chloroform on your body. Chloroform is a separate chemical compound that is not formed by simply having chlorine from a pool on your body.
To extract benzoic acid from chloroform, first dissolve the benzoic acid in water. Then, add chloroform to the mixture and shake well to allow for the benzoic acid to transfer to the chloroform phase. Finally, separate the two phases and evaporate the chloroform to obtain the benzoic acid.
When water and chloroform are mixed, they will form two separate layers due to their different densities. Chloroform is not soluble in water, so they will not mix homogeneously. Chloroform tends to settle as the bottom layer since it is denser than water.

Chloroform is a colorless liquid with a sweet smell, while carbon tetrachloride is a colorless liquid with a strong odor. Chloroform is used in medical and industrial applications, while carbon tetrachloride was once used as a solvent but is now considered toxic and harmful to health.
A separating funnel is especially designed for separating liquids such as chloroform. So long as a person follows the instructions that came with it and does pour the liquid carefully then it will work.
