How do you separate iodine and sodium iodide?

Answer 1

Ah, separating iodine from sodium iodide is like creating a happy little separation. You can do this by adding water to the mixture, which will dissolve the sodium iodide but not the iodine. Then, you can use a filter to separate the solid iodine from the liquid sodium iodide solution. Just remember, there are no mistakes in science, only happy accidents.

Answer 2

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 sodium chloride

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.

Answer 3

You can separate iodine from sodium iodide by a process called fractional crystallization. This involves dissolving the mixture in water, heating it to allow the iodine to vaporize and collect separately, and then cooling the solution to crystalize the sodium iodide.

Answer 4

Collect iodine resulted from the sublimation/distillation.

Answer 5

The easiest way is to warm gently. Iodine sublimes and crystals will condense on a cold object leaving behind sugar.

Answer 6

Common salt is soluble in water.
