  • Molecular Weight by Freezing Point Depression

    The melting point is the temperature at which the crystal structure of a solid breaks down with increasing entropy (+ΔS). Solute particles introduced into the solvent increases the entropy, and therefore decreases the temperature of the solution in order to reach the melting or freezing point of the solution...
