Interpretation: The expected freezing point of LiFsolution has to be determined.
Concept introduction:
Colligative properties: Properties of solutions which having influence on the concentration of the solute in it. Colligative properties are,
Decrease in the vapor pressure
Increase in the boiling point
Decline in the freezing point
Osmotic pressure
Decline in the freezing point is huge when solute is an electrolyte than when solute is nonelectrolyte. Therefore, change in freezing point is calculated by using the equation,
ΔTfp=Kfpmsolutei
where,
Kfp is the molal freezing point depression constant.
i is van’t Hoff factor
van’t Hoff factor, i: it is the relation between change in in freezing point measured and change in in freezing point calculated. It indicates the total number of ions that are produced.
Molality (m): Molality is the number of moles of solute present in one kilogram of solvent.
