filter the salt freeze the mixture evaporate the water pour the water out of the container
I gave my students this multiple choice question: In an experiment, water and salt are mixed together. What is the best way to separate the salt from the water?

Only one answer is correct among these 4 choices:
- filter the salt
- freeze the mixture
- evaporate the water
- pour the water out of the container

Could you tell me which one is correct?

evaporate the water
