Boil the solution till all the water has evaporated, this would leave the sodium chloride behind.

It's been a little while since I've taken chemistry, but I'll try to help you out. To seperate the sodium chloride (NaCl, table salt) from water (H20), boil the water at 212 degrees Farenheit or 100 degrees Celsius until all of the water has evaporated. Once that is done the only thing that should be left is the solid sodium chloride. The NaCl should not evaporate since it's BP, boiling point, is higher than that of water.

If you don't need to have the water any more, you can boil the solution and you will be left with the sodium chloride after the water evaporates

Boil the water until all the water has boiled away, leaving only the salt (sodium chloride)

Distill the solution. Boil the water and trap the vapour. When it cools it will be pure water. The crystalline powder left in the original container will be salt (NaCl).

boil the water until it is a quarter of it's original volume,
test the result with glass rod.
if the thick liquid immediately turn into crystals, then you are done.
let the mixture cool off in the room temperature.
when it all dried up, you'll get your salt.

As everyone else says - boil it off. If you need to keep the water too - just distill it, so in the original flask you'll have your salt, and in the end flask will be your purified water.

Boil the water off.

let it stand in a bottle..........for 24 hours the sodium chloride will settle to the bottom... the water on top

boil the solution at 100 C, the HOH with evap. and leave NaCl
