Zinc reacts with iodine. Powdered zinc metal (Zn) and iodine (I2) are mixed together and placed in a watch glass. A drop of water is used to initiate the synthesis reaction: Zn + I2 -> ZnI2. It is an exothermic redox reaction that produces a lot of heat so that iodine sublimates and forms a violet vapour. | |
