Freezing Point Depression of A Solution.
The freezing point of a solution is always lower than that of pure solvent.
A specifi c instrument (cryoscope) will determine freezing-point depression in experimental way.
If cryoscopic constants of solvent are known, the molecular mass of dissolved substances can be determined.

OBJECTIVES
Determining the value of freezing-point depression of a solution after the dissolution of a strong electrolyte (NaCl) in water.
Comparing experimental and theoretical values for this concentration will lead to determine the number of ions involved in electrolyte dissociation
Determining the apparent molar mass of a non-electrolyte from the value of freezing-point depression
