Expert Solution

Step 1: Explaining the concept of conductivity, freezing point and boiling point

Conductivity: Conductivity is a measure of a solution's ability to conduct an electric current. The primary factor affecting conductivity is the concentration of ions in the solution. The greater the concentration of ions, the higher the conductivity.
Freezing Point: The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase under standard atmospheric pressure. The addition of non-volatile solutes lowers the freezing point of pure solvent.
Boiling point: The boiling point of a substance is the temperature at which it changes from a liquid phase to a gaseous phase under standard atmospheric pressure. The addition of non-volatile solutes increases the boiling point of pure solvent.
