- By using water followed by filtration
- By using water followed by sublimation
- Boiling
- By using CS2followed by crystallization
Hint:
By using water followed by filteration.
The correct answer is: By using water followed by filtration
Salt is soluble in water but chalk powder is insoluble in water. Hence, salt gets dissolved in water and chalk powder can be separated by filtration.
