The freezing point of a solution will
decrease
and the boiling point will i
ncrease with an
increase in the amount of dissolved
solute.
Solutes affect the boiling point of the
solvent because it is the temperature where vapor pressure of the solvent becomes
equal to the external atmospheric pressure. Increased amount of solutes will
cause the solvent to take more time and temperature to make vapor pressure and
causes the boiling point to increase.
Increased solutes decreases freezing point by interfering with the frozen solution's
crystal structure. Temperatures will have to be colder to overcome it.
