Principle:I2 is soluble in ethyl alcohol (C2H5OH) while NH4Cl is not.
Process 1 : Dissolution in a special solvent,i.e.Ethyl alcohol.
Iodine will dissolve within the solvent and NH4Cl crystals will be found floating on the surface of the liquid.
The mixture will be filtered and NH4Cl will be obtained on the filter paper.
The subsequent filtrate will be evaporated to get the precipitate of Iodine.
