Chloroform and silver powder react with each other and exchange the ions with each other to form acetylene molecules which are also called ethyne and silver chloride. The molecule C2H2is called acetylene which is a colourless gas with no odour.
Note: The Ag powder is synthesized by reducing silver nitrate with glycerol and here glycerol acts as the solvent for the reaction. The above given reaction can be proceeded with tribromomethane (bromoform) or triiodomethane (iodoform) since the structure of iodoform and bromoform resembles chloroform.
