Question

$0.1\, M$ solution of glucose has same increment in the freezing point than $0.1\, M$ solution of urea. $K_f$ for both has same value.

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

Answer 1

Answer: (A)

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Answer 2

Depression in freezing point is a colligative property, depends on the number of particles present in the solution. As both 0.1 M solution of Glucose and 0.1 M solution of urea contain same number of moles (number of particles) therefore, both have same K .
