How do you separate iodine from salt?

If your talking about separating a mixture of Iodine and salt
(Sodium Chloride) then to separate them the easiest way would be to
mix the mixture in water which will cause the sodium chloride to
dissolve (along with a very small amount of iodine), then you just
pour off the water and viola, your iodine is left at the bottom.
Repeat this process again to make sure you get rid of all the
Note: ~37.5 grams of sodium chloride will dissolve in 100mL of water at room temperature ~21 degrees Celsius. So you may need to repeat the process depending on how much salt is mixed with the iodine.
Note: the iodine may form a suspension in the water, if this is the case allow it to sit for a while to form the sediment at the bottom, if it doesn't you can use filter paper when you pour out the water.
