The depression of freezing point is directly proportional to

Depression in freezing point or cryoscopy

Cryoscopic constant is the depression in freezing point produced by :

The two isomers X and Y with the formula Cr(H_(2)O)_(5)ClBr were taken for experiment on depression in freezing point. It was found that one mole of X gave depression corresponding to 2 moles of particles and one mole of Y gave depression to 3 moles of particles. The structural formulae of X and Y raspectively are

MX_(2) dissociates into M^(2+) and X^(-) ions in an aqeous solution, with a degree dissociation (alpha) of 0.5. The ratio of the observed depression of freezing point of the aqueous solution to the value of the depression of freezing point in the absence of ionic dissociation is

Statement - I. Greater the molal depression constant of the solvent used less in the freezing point of the solution. Statement - II. Depression in freezing point depends upon the nature of the solvent.
