Being a student of chemistry today I want to share the experiment of Iodine, Zinc and water.
First of all we need a Pitric dish , Zinc Powder, Iodine and water.
Put the Iodine in Pitric dish we can also used china dish instead of Pitric dish.then mix slowly and carefully zinc powder in it wait for some time then put drop of water in it you will see the purple smoke.
In Reality the purple smoke is the Iodine in gaseous state.
As this reaction is Exothermic in nature the large amount of heat is released so need to careful.
The Reaction is.....
Zn + I2---------------- ZnI2
