Question

Explain depression of freezing point of a solution on the addition of solute.Show that depression in freezing point is colligative property?

Answer 1

Freezing point is a point at which the first particle of the substance start forming crystal.

Depression in freezing point can be explained as ,if we take glass of water and put it in the freezer taking temperature as 0 C (freezing point)the first crystal of water will start to form.if we now add sugar to the water such that sugar is 100% disosiates then if we keep it  in freezer at 0 C ,no crystal will be form because if one crystal start to form the molality of the solution changes which results in increase in freezing point
