The Reaction of Iron Chloride

Chlorine reacts very intensely with metals.

We filled a high glass with chlorine gas and our assistant, Christian, brought some iron wool. He took a small piece of it and set it on fire with a Bunsen burner.

 

 

 

 

 

 

He threw the burning iron wool into the glass whereupon the chlorine gas instantly turned reddish-brown. The iron wool burns and iron chloride is created.

 

 

 

 

 

 

Iron chloride has a brown colour and is a solid.

 

 

 

 

 

 

A similar experiment can be performed with zinc: The zinc is heated and put into the chlorine. White zinc chloride is produced.
