What is the primary reason for the increase in boiling point when a solute is added?

Step 1: Understand that boiling point is the temperature at which a liquid turns into a gas.
Step 2: Know that a solvent is a liquid that can dissolve a solute (like salt in water).
Step 3: When you add a solute to a solvent, it mixes in and changes how the solvent behaves.
Step 4: One important change is that the vapor pressure of the solvent decreases. Vapor pressure is the pressure of the gas above the liquid.
Step 5: Because the vapor pressure is lower, the solvent needs to be heated to a higher temperature to reach the point where it can boil.
Step 6: Therefore, adding a solute raises the boiling point of the solvent.
