英文小作文:
Chloroform is a colorless liquid with a pungent odor and a taste similar to that of ether. It is used in laboratory experiments to dissolve substances that are difficult to dissolve in water or other solvents commonly used in the laboratory. Chloroform is also used in medicine as an anesthetic and in the extraction of substances from mixtures using chloroform-ether extraction. However, chloroform is also a toxic substance that can cause serious harm to the human body if used improperly or in large amounts. Therefore, it is important to use chloroform carefully and follow safety precautions when using it in the laboratory or at home.
