Final answer:
The best way to get the salt out of a salt-water solution is to boil away the water through evaporation.
Step-by-step explanation:
The best way to get the salt out of a salt-water solution is to boil away the water. When the water is boiled, it turns into vapor and escapes into the air, leaving the salt behind. The salt can then be collected from the container once all the water has evaporated. This process is called evaporation.
Pouring the salt-water solution through a filter would not work because the salt particles are too small and will pass through the filter. Using a magnet to pull out the salt particles would also not work because salt is not magnetic. Freezing the salt-water solution would only separate the water from the salt temporarily, and the salt would dissolve back into the water when it melts.
