Mix the sand/salt mixture with distilled or deionized water, which should dissolve the salt. Then pour the whole thing through piece of filter paper. The salty water will go through the filter, while the sand will be caught. Boil off the water to recover the salt.
Naphthalene can be separated from common salt by sublimation since naphthalene sublimes at a lower temperature than common salt. By heating the mixture, naphthalene will turn directly from a solid to a gas, leaving behind the common salt as a solid residue. The naphthalene gas can then be cooled and collected back as a solid.
The mixture of sugar-salt solution can be separated by evaporation. If the water is completely evaporated we will get separated sugar from the mixture. If we dissolve the mixture in alcohol we will get the salt separated while sugar will be dissolved in alcohol. After that, the solution is further filtered and salt will be the residue of the solution.
A mixture of common salt and powdered sulfur can be separated using water. Since salt is soluble in water while sulfur is not, adding water to the mixture allows the salt to dissolve. The undissolved sulfur can then be filtered out, leaving a solution of saltwater. Finally, the salt can be recovered by evaporating the water.

Ammonium chloride and common salt can be separated using their different solubilities in water. Since ammonium chloride is more soluble in water than common salt, you can dissolve the mixture in water and then evaporate the solution. Ammonium chloride will remain dissolved in the solution, while common salt will precipitate out as a solid.
Sand+salt: a heterogeneous mixture.
A saltwater mixture can be separated by evaporating the liquid. When the water evaporates, the salt is left behind as a solid residue. This process is commonly used to obtain salt from seawater or to separate dissolved solids from water in industrial processes.

salt and water
A mixture can be separated by physical properties such as differences in boiling points, solubility, density, or magnetic properties. For example, a mixture of salt and sand can be separated by dissolving the salt in water and then filtering out the sand, as salt is soluble in water and sand is not.
Yes, salt can be separated from a mixture through various methods. One common method is evaporation, where water is heated to evaporate, leaving salt crystals behind. Another method is filtration, which can be used if salt is mixed with insoluble impurities. Additionally, salt can be separated from seawater through processes like distillation or reverse osmosis.
