Question:

(5) True or False: The calculated Ki value should be different for the two determinations. Explain why or why not:
(5) True or False: The calculated Ki value should be different for the two determinations. Explain why or why not:

Answers

Solution:

True

Kf (molal depression constant) is calculated by dividing depression in freezing point (ΔTf) by molality of the solution.

Kf = ΔTf / m

So, its value is both depends upon ΔTf as well as molal concentration. If m is higher, then calculated Kf is low and high value of Kf corresponds to lower molality.
