Preparation And Properties Of The Halogens (1959)
This film discusses the halogens, specifically chlorine, bromine, and iodine, detailing their preparation from naturally occurring salts and their chemical properties. The film demonstrates various reactions to produce chlorine and tests for its presence, such as using starch iodide paper and litmus paper. It also covers the preparation of bromine and iodine, highlighting their solubility and reactions with metals and other compounds. The halogens are compared based on their reactivity, with chlorine being the most active, followed by bromine and then iodine.
