The freezing point of a liquid will change when a solute is added. Explain how the addition of salt impacts the boiling point of water. Calculate the freezing point change for a given concentration. Given that water’s freezing point is 0.00ºC and the freezing point depression constant (Kf) is 1.86 ºC･kg/mol, calculate the freezing point depression for a 2.75 molal solution (moles/kg) of NaCl in water. Assume ideal behavior of the ions.   Please use the correct number of significant figures! Thank you!

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
