Question
______ is a process that can be used to obtain a very pure solid dissolved in a liquid.
- Centrifugation
- Filtration
- Distillation
- Dilution
Hint:
None is correct.
The correct answer is: Distillation
Crystallization is a natural process which occurs as materials solidify from a liquid, or as they precipitate out of a liquid or gas. This can be caused by a physical change, such as a temperature change, or a chemical change such as acidity.
