Question

2. Which one of the following method is used to separate salt from sea water?
d. Evaporation b. Centrifugation Sublimation d. All of these
​

Answer 1

The answer is simple: through evaporation. When you evaporate salt water (either with natural or artificial heat), only the water forms water vapor, but the salt remains. With this in mind, it's pretty easy to separate salt from water with the kinds of common materials you can have around the house.
