we can separate them by sublimation as iodine sublimes on heating.
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
Yes, the sieving method can be used to separate iodine crystals and iron fillings. This method relies on the difference in particle size between the two substances to effectively separate them through a sieve or mesh screen. The smaller iodine crystals will pass through the sieve, while the larger iron fillings will be retained on top, allowing for separation.
Since each substance has unique chemical and physical properties, use these to separate each... specifically we will use the solubility of these substances. First, drain the liquids from the mixture (this will contain saltwater, and a "tincture" or solution of alcohol and iodine) leaving only the sand and iron filings (which have no solubility in either water or alcohol). Next, use a magnet to separate the iron filings from the sand - (2 down - 4 to go) Since the salt is dissolved in water (it does not dissolve in alcohol) , and the iodine is dissolved in the alcohol (it does not dissolve in water), separate the two (the alcohol/iodine solution is the one floating on top of the saltwater as it has a lower specific gravity) Then, distill the saltwater into fresh water and salt crystals (4 down - 2 to go) Similarly distill the tincture of iodine into alcohol and iodine crystals (all 6 complete)
The solute would be iodine, and the solvent would be tincture
To form a heterogeneous mixture of sugar and salt crystals, you can simply mix the two substances together in a container. The sugar and salt crystals will not dissolve into each other as they have different chemical properties, creating a visible separation in the mixture.

Solid iodine can be found as pure crystals.

It turns clear and then turns to a dark blueish purple.It would be considered as a chemical reaction.It also takes a while for it to go though this process, but it's worth it.Nora (:

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.
One way to separate iron filings from a mixture of salt crystals and water is to use a magnet. The iron filings will be attracted to the magnet, allowing for easy separation. Another method is to use filtration. By pouring the mixture through a filter paper, the iron filings will be retained on the filter paper while the salt crystals and water pass through.
First add water to mixture the ammonium chloride will dissolve in the water but the iodine does not. Filter out the iodine using filtration then use evaporation or distillation to obtain the ammonium chloride.

A homogeneous mixture would be the hardest to separate because the components are evenly distributed at a molecular level, making it difficult to physically separate them.
To make a pure sample of iodine, you can start with a mixture containing iodine and other substances, then use a process like sublimation to separate the iodine from the other components. Sublimation involves heating the mixture to allow the iodine to vaporize and then cooling it to condense the iodine back into solid form. This process helps to obtain a pure sample of iodine.
