If molarity of the dilute solutions is doubled ,the value of molal depression constant`(K_(f))`will be:

Options

A. Unchanged
B. Doubled
C. Halved
D. Tripled

Answer

A

Explanation

If molality of a dilute solution is doubled , the value of molar depression constant `(K_(f))` will be unchanged because the value of molal depression constant will depend only on number of solute and solvent particle , as it is colligative property .
