Reactions of Metals with Iodine - Manganese
Manganese is mixed with iodine. Notice that the powdered manganese is black, and the iodine is also nearly black. Again there is no reaction just upon mixing the solid materials but as soon as a few drops of water are added, a reaction does take place. Again the reaction is vigorous, but this time there is no flame. By comparison with the aluminum reaction, the manganese reaction was not as vigorous.
