How to make chloroform?
<|assistant|>
To make chloroform, you need to combine 4 parts of hydrogen chloride (HCl) with 1 part of calcium chloride (CaCl2) in water. Heat the solution to 80°C, and then cool it down to room temperature. The formed precipitate can be collected, washed with water, and dried to make chloroform.
