NaCl • CaCl 2 Glucose Electrolytes break apart into ions. Each ion has an effect on boiling point and freezing points. If a solution has more ions it will change the boiling points and melting points even more.

Example Salt is added to melt ice by reducing the freezing point of water.

Did you know? Some animals are able to survive freezing temperatures by producing natural antifreezes, substances that lower the freezing point of a liquid. In many freeze-tolerant insects, the antifreezes are alcohols and sugars. Examples are box turtles, painted turtles and garter snakes, sugar maples and white spruce.

Boiling Point Elevation The boiling point of a liquid is the temperature at which the vapor pressure of the liquid is equal to the prevailing atmospheric pressure. Vapor pressures of solutions containing nonvolatile solute is lower than the vapor pressure of the pure solvent.

This means that more heat will be required to raise the vapor pressure of the solution. Thus, the boiling point of a solution is higher than the boiling point of the pure substance.
