Reactions of Metals with Iodine - Zinc
Granular zinc is mixed with iodine and there is no reaction when the two dry solids are mixed together. When water is added to this mixture, there is a reaction approximately as vigorous as the reaction of the manganese with the iodine, showing that zinc and manganese are roughly equivalent in reducing strength, and are stronger than iron and nickel, but not quite as strong as aluminum.
