Interpretation Introduction

Interpretation: The molality or molarity dependent on temperature is should be explained and reason for the usage of molality in freezing-point depression and boiling point elevation calculations are explained.

Concept introduction:

Elevation of boiling point:
The boiling point of the solution is increases when the solute is dissolved in the solvent are called Elevation of boiling point. It is one of the colligative Properties thus,

                                           $ΔT = iKbmsolute......(1) ΔT is boiling-point elevation Kb is molal boiling-point elevation constant m is molality of the solute i is the van't Hoff factor$

Depression in freezing point:
The freezing point the solution is decreases when the solute is dissolved in the solvent is called Elevation of boiling point. it is one of the colligative Properties thus

                                 $ΔT = iKfmsolute......(2) ΔT is boiling-point elevation Kf is molal freezing-point depression constant m is molality of the solute i is the van't Hoff factor$

Molarity:

                  The gram moles of solute in liter of solvent is called molarity and in is the term of concentration.

                            $Molarity = solute mass gsolvent volume L$

Molality:

                  The gram moles of solute in kilogram of solvent is called molality and in is the term of concentration.

                            $Molality = solute mass gsolvent mass kg$
