The Chemistry of the Halogens - Purdue University

The synthesis of fluorine escaped the efforts of chemists for almost 100 years. Part of the problem was finding an oxidizing agent strong enough to oxidize the F-ion to F 2.The task of preparing fluorine was made even more difficult by the extraordinary toxicity of both F 2 and the hydrogen fluoride (HF) used to make it.. The best way of producing a strong reducing agent is to pass an electric
