Will adding a solute to a solvent raise the freezing point of the solvent?

Usually no............


#"Freezing point depression"# is a so-called #"colligative property"#, and the depression of the freezing point (i.e. #"fusion point"#) of the SOLVENT is proportional to the numbers of species of solute in that solution.

Sometimes this freezing point depression can give an estimate for the molecular mass of the solute in SOLUTION, and it can do this by very simple means with a solvent like cyclohexane, and a good Beckmann thermometer.
