How would you extract solid salt from the soluble salt solution?

Answer 1

I think perhaps the question was more literal than theoretical, evaporation is of course the theoretical answer in general, but not an actual how to answer. Though running salt water over long distances inside clear tubes that have a black internal floor helps create heat allowing light inside, and allowing the vapor to condense and run down into internal gutters and out is the easiest low power method for volume without membranes or heaters. for home and kids, the old string hanging from a pencil into a glass of salt water works well to watch it happen, or for a camper on the salt flats or near the beach who want a container of salt for dinner that is the easiest. Use a table cloth, cotton, and soak it it the salt water and allow it to dry completely, place the cloth in a large zip lock bag and shake the salt loose. salt for dinner same day.

Answer 2

You can extract solid salt from a soluble salt solution by evaporating the water. Simply heat the solution to boil off the water, leaving behind the salt as a solid residue. Once all the water has evaporated, you can collect the solid salt that remains.
