The temperature at which the solution boils is raised
Adding solute to pure solvents will cause the solute to dissolve in the solvent, forming a solution. This process can alter the properties of the solvent, such as its boiling point, freezing point, and osmotic pressure, depending on the amount and nature of the solute added.
The addition of a non-volatile solute elevates the boiling point of a solution (in addition to the depression of freezing point). The formula is ΔT = Kbm where ΔT is the change in temperature, Kb is the ebullioscopic constant, and m is the molality (not molarity) of the solution.
Adding a solute to a solvent will increase the mass of the solution because the solute molecules are being introduced, contributing to the total mass. The increase in mass will be proportional to the amount of solute added.
Liquids in a pure state have a specific boiling point.Water, for example, boils at 100 oC at 1 atm. However once there are impurities in the liquid the boiling point will be elevated. The degree of elevation depends on the quantity of impurity in the liquid.
The similarities between the solute and solvent can lead to stronger interactions between them, increasing the boiling point of the solution due to enhanced solute-solvent cohesion. Conversely, dissimilarities may reduce these interactions, lowering the boiling point by weakening the solute-solvent bonds. Overall, the impact on boiling point depends on the specific chemical characteristics of the solute and solvent involved.
boiling point is increased and freezing point is decreased
the temperature at which the solution freezes is lowered.

Adding a solute to a solution, or some liquid, causes the boiling point to increase. Think about water, sometimes people throw salt in their water when they're boiling noodles. This causes the boiling point to increase so the water is actually at a higher temperature (although most of the time the amount of salt added isn't nearly enough to cause any measurable change).

Colligative properties are dependent on the number of solute particles and not the type of solute. One common coligative property is boiling point elevation, where adding a solute to a solvent increases the boiling point of the solution compared to the pure solvent. This effect is commonly observed when salt is added to water, as the boiling point of the saltwater solution is higher than that of pure water.
When a solute is added to a solvent, the boiling point is raised according to the equation ΔTb=Kbm. Thus, the boiling temperature of a solution can be described by: Tb(solution)=ΔTb + Tb(pure solvent). However, for the purposes of this question, adding a solute increases the boiling point of a solution.

Adding more solute to a saturated aqueous solution causes the excess solute to precipitate out of the solution as solid particles. This process is known as precipitation and helps to decrease the concentration of the solute in the solution, allowing for more solute to dissolve.
