We dissolve #25*g# mass of the following solutes in equivalent volumes of water. Which solutions will display the GREATEST freezing point depression?
Freezing point depression depends on the NUMBER of particles in solution; therefore, maximum depression is observed for the solute with least molar mass.
And the solute with least molar mass is clearly sodium fluoride:
Clearly, when the given mass of sodium fluoride dissolves (which will cause a change in
