Question

Assertion:

Distillation is good for separating a liquid from a solution

Reason:

Distillation method works because the water evaporates from the solution, but is then cooled and condensed into a separate container.

• A. Both assertion and reason are valid, and the reason is the valid explanation for assertion
• B. Both assertion and reason are valid, but reason is not the valid explanation for assertion
• C. Assertion is valid, but the reason is invalid
• D. Both assertion and reason are invalid

Answer 1

The correct option is A

Both assertion and reason are valid, and the reason is the valid explanation for assertion

The correct option is (A):

Explanation for assertion statement:

Distillation:

1. Distillation is basically a separation technique which is actually used for the extraction of the mixture solid in a liquid.
2. It is basically the process of heating the liquid to form the vapors and then condensing in order to get back the liquid.
3. So, the liquid which is obtained by performing the condensation of vapors is called the distillate .
4. For example : Water can be separated from the salty water by simple distillation.

Explanation for the reason statement:

1. So, as distillation is the method for separating a liquid from a solution.
2. Therefore, this method works best because of the evaporation of water from the solution and then which is further cooled and condensed to a separate container.
3. Example: On the evaporation of salt solution, water after getting cooled will start getting collected in the separate container leaving the salt behind .
4. Hence, the assertion and reason are valid, and also the reason is correct explanation of assertion statement.

Explanation for the incorrect answers:

Option (B):

1. Both assertion and reason are valid statement, as distillation is a process that is used for separating the liquid from the solution
2. And also after the evaporation from the solution, it is cooled or condensed to another container.
3. Also reason is the correct explanation for the assertion.
4. Hence, this option is incorrect.

Option (C):

1. Both assertion and reason are valid statement, as distillation is a process that is used for separating the liquid from the solution
2. And also after the evaporation from the solution, it is cooled or condensed to another container.
3. Hence, this option is incorrect.

Option (D):

1. Both assertion and reason are valid statement, as distillation is a process that is used for separating the liquid from the solution
2. And also after the evaporation from the solution, it is cooled or condensed to another container.
3. Hence, this option is incorrect.

Therefore, the correct option is (A): Both assertion and reason are valid, and the reason is the valid explanation for assertion.
