Question

$NaCl$ is less soluble in heavy water than in ordinary water. Dielectric constant of ordinary water is more than that of heavy water.

• A. If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion
• B. If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion
• C. If Assertion: is true but Reason: is false
• D. If both Assertion: and Reason: are false

Answer 1

Answer: (A)

If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion

Answer 2

$NaCl$ is less soluble in heavy water than in ordinary water because dielectric constant of ordinary water (i.e., $81$ ) is more than that of heavy water (i.e., $80$ ).
