Ammonium chloride is soluble in water and the sand can be separated from the solution by filtering.
Add sufficient water to dissolve the ammonium chloride. Neither the iodine nor the sand will dissolve.Filter out the solids.Evaporate the ammonium chloride from the solution.Heat the solids gently in a retort to sublimate the iodine and recover it.

One way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
Sodium chloride is soluble in water.
Ammonium chloride is an inorganic compound.
One suitable technique to separate sand from ammonium chloride is filtration. The mixture can be dissolved in water, allowing the ammonium chloride to go into solution while the sand remains as a solid. The solution can then be passed through a filter to separate the sand from the dissolved ammonium chloride.

heat the mixture until you no longer see white fumes, then stir the mixture to make sure all of the ammonium chloride is sublimed (solid moved to a gaseous state without passing through the liquid phase. All that should be left is the sand.
NaCl, table salt, and ammonium chloride will both dissolve in water. Sand is only sparingly soluble in water. If you want to further separate ammonium chloride from sodium chloride, you will need to dry the resulting solution. The sodium chloride will precipitate out first. The ammonium chloride will remain in the supernatant and can be poured off leaving the sodium chloride crystals behind.
To separate ammonium chloride from a mixture of ammonium chloride and potassium chloride, you can use the process of sublimation. Ammonium chloride sublimes at a lower temperature compared to potassium chloride. By heating the mixture, the ammonium chloride will directly change from a solid to a gas, leaving behind the potassium chloride. The resulting gas can be condensed back into solid form for collection.
Heat it until the ammonium chloride sublimes. Then add distilled water to what's left, stir, allow the solid to settle to the bottom of the dish, and decant the liquid. Repeat that 3 times. That'll extract the sodium chloride (salt) from the silicon dioxide (sand), because the NaCl is soluble in water. Then heat the salt water solution carefully until all the water is evaporated. Then heat the sand to dry it out.
Heating the mixture ammonium chloride is decomposed after 315 oC.
By sublimation
1. Run a magnet over the mixture. Iron will be attracted to the magnet, hence allowing it to be separated.2. Sublime/crystallise the ammonium chloride through heating. 3. Dissolve what you have left in water. Now filter the mixture through a filter funnel with filter paper. The residue on the filter paper would be sand.
Ammonium chloride sublimes when heated, transitioning from a solid directly to a gas without passing through a liquid phase. Sand does not undergo sublimation as it does not turn into a gas when heated, but rather melts at high temperatures.
because
Ammonium chloride is water-soluble whereas copper oxide is not. You can separate them by dissolving the mixture in water, then filtering it. The filtrate solution will contain ammonium chloride and the residue will contain copper oxide.
