Freezing point and boiling point of the solutions to be calculated. 5g NaCl into 25g water Concept introduction: Freezing point: Freezing point is defined as the temperature at which liquid into solid. Boiling point: Boiling point is temperature at which the liquid into gas. Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent. Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.

Freezing point and boiling point of the solutions to be calculated.
5g
NaCl into 25g water
Concept introduction:
Freezing point: Freezing point is defined as the temperature at which liquid into solid.
Boiling point: Boiling point is temperature at which the liquid into gas.
Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent.
Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.

Freezing point and boiling point of the solutions to be calculated.
2.0g
Al(NO3)3 into 15g water
Concept introduction:
Freezing point: Freezing point is defined as the temperature at which liquid into solid.
Boiling point: Boiling point is temperature at which the liquid into gas.
Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent.
Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.
