Question

Which of the following statement is true.

Sodium chloride from its solution in water can be separated by filtration.

• A. True
• B. False

Answer 1

The correct option is B False

1. Evaporation: It is a process by which water is transformed from liquid to a gaseous state.
2. It is the process of separating any substance from its solution by removing water.
3. Filtration: It is technically defined as the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter.
4. It is used to separate insoluble solids in a liquid.
5. For example, it is used to separate sand from the mixture of sand and water.
6. Sodium chloride is soluble in water and makes a homogeneous solution.
7. That is a true solution which can't be separated by using filtration.
8. But sodium chloride from its solution in water can be separated by using the evaporation method.

Hence, the given statement is false.
