Explanation:
Separating Sand and Salt
Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.
Answer:
One method of separating salt and sand is based on solubility. If a substance is soluble, it means it dissolves in a solvent. Salt is an ionic compound that is soluble in water. Sand is not.
Pour the salt and sand mixture into a pan.
Add water. You don't need to add a lot of water. Solubility is a property that is affected by temperature, so more salt dissolves in hot water than cold water. It's okay if the salt doesn't dissolve at this point.
Heat the water until the salt dissolves. If you get to where the water is boiling and there is still solid salt, you can add a bit more water.
Remove the pan from heat and allow it to cool until it's safe to handle.
Pour the salt water into a separate container.
Now collect the sand.
Pour the salt water back into the empty pan.
Heat the salt water until the water boils. Continue boiling it until the water is gone and you're left with the salt.
