Freezing Point of Solutions Nicole Marshall*, Nathalee Delgado Chemistry 101, Los Angeles Harbor College Abstract-       The purpose of this laboratory experiment is to find the freezing points  of the following aqueous solutions: pure water, methanol and sodium chloride.  Experimentally our results were within close range of the calculated freezing  points of the various solutions.   Introduction- The freezing point of a solution is the temperature at which the liquid  congeals into a solid state at a given pressure.  A solution is a combination of two  of more substances that are uniformly mixed together.  A solution would  generally have a measurably lower melting point than a pure solvent.  The extent  that the freezing point is lowered is dependent on the molecular concentration of  the solute and whether the solution is an electrolyte.  Non-electrolytes solutions  have been found to have higher freezing points for a given concentration of
