Which of the following factors will affect the freezing point of a solution? The concentration of the solute only.

Neither the concentration nor type of solute.

The type of solute used only.

Both the concentration and type of solute.

The freezing point of the solvent in a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).

Generally, pressures lower than 1 atmosphere lower the temperature at which a substance freezes, but for water, a higher pressure gives a lower freezing point. The force from a pressure change figures into the molecular forces already at play in a substance.
