filtration
The others, while possible, are not practible.
Decamting is a possibility, just pour off the salt water. However, getting all the moisture off the iodine would be tricky.
A mixture of iodine solid and sodium chloride ( Hint: iodine is not soluble in water)
What method(s) can I use to separate the mixtures?
Filtration
Evaporation
Centrifugation
Decant
Magnetic attraction
Paper chromatography
Distillation
Can you use filtration? centrifugation? decantation?
filtration is the only possible method.
I disagree that filtration is the ONLY possible method. That may be the best; it even may be the quickest, but I don't think is the the only method. I could decant and dump the I2 crystals onto a paper towel to soak up the water. Or centrifuge and dry the same way. Presto.
If we worry about the small amount of NaCl that might be on the I2 crystals, we could wash the I2 once (or more if needed) and dump onto paper.

To separate a mixture of iodine solid and sodium chloride, you can use the following methods:
1. Filtration: This method can be used if the mixture contains larger particles. In this process, a filter paper or a sieve is used to separate the solid particles from the mixture. Since iodine is not soluble in water, it will remain on the filter paper while sodium chloride can pass through.
2. Evaporation: If the mixture contains a liquid component, you can use evaporation to separate it from the solid components. Heat the mixture to evaporate the liquid, leaving the solid iodine and sodium chloride behind.
3. Centrifugation: This method is suitable when the mixture contains solid particles that settle at the bottom over time. By spinning the mixture in a centrifuge, the denser particles, such as sodium chloride, will settle at the bottom, allowing you to separate them from the lighter particles like iodine.
4. Decantation: If the mixture is a suspension (liquid with solid particles dispersed in it), you can let it settle and then carefully pour off the liquid without disturbing the settled solids. This method works well if the solid particles are larger and settle quickly.
5. Magnetic attraction: If one of the components in the mixture is magnetic, such as iron filings or nickel, you can use a magnet to separate it from the non-magnetic components. However, since iodine and sodium chloride are not magnetic, this method is not applicable in this case.
6. Paper chromatography: This technique can be used to separate mixtures of substances that have different solubilities in a particular solvent. However, since iodine is not soluble in water, it would not be separable from sodium chloride using paper chromatography as the solvent system used would not dissolve the iodine.
7. Distillation: This method can be used if the mixture contains a liquid component that has a different boiling point than the other component. When the mixture is heated, the component with the lower boiling point evaporates first, and then it condenses into a separate container as it cools. However, this method is not suitable for separating iodine and sodium chloride, as they do not have significantly different boiling points.
The most appropriate methods to separate iodine solid and sodium chloride from each other would be filtration and evaporation.
