Can't I just add a chemical to water to remove the salt?
Some I get asked many many times each year, a better question is can you do it economically!
A chemical method of separating salt and water involves adding decanoic acid to salt water. The solution is heated. Upon cooling, salt precipitates out of the solution, falling to the bottom of the container. The water and decanoic acid settle into separate layers, so the water can be removed.
