The boiling point rises and the freezing point lowers.The reason being, when a solute dissolves in a solvent, the solute molecules wedge themselves between the solvent molecules. In order for the solvent to freeze, its molecules have to get close enough together to form a solid. However, the solute molecules are in the way. As a result, it requires much colder temperatures for the solvent molecules to form a solid, despite the hindrance of the solute's molecules. The same sort of thing happens when trying to boil the solvent, only instead of holding the solvent molecules apart, the solute molecules end up holding them together, preventing them from boiling. Therefore, a more energy is needed to break the bond between solvent and solute, which allows the solvent to boil.

What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
What happen when solutes and solvent are mixed?
When solutes (substances dissolved in a solution) are mixed with a solvent (the substance in which the solutes dissolve), the solutes disperse evenly throughout the solvent due to Brownian motion and intermolecular interactions. This results in the formation of a homogenous mixture called a solution. The solutes remain dispersed in the solvent unless a physical or chemical change occurs.
Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
What is the tendency of a solute to change the boiling of a soild called?
The tendency of a solute to change the boiling point of a solvent is called boiling-point elevation. This occurs because the presence of the solute disrupts the solvent's ability to form vapor, therefore requiring more heat to reach the boiling point.
How a solute affects the boiling point of a solution?
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.
How adding solute changes the properties of a solvent?
Adding a solute to a solvent can change its properties by altering the boiling point, melting point, viscosity, and osmotic pressure. The presence of solute particles disrupts the solvent's ability to vaporize or freeze, leading to changes in these properties. The more solute added, the greater the impact on the solvent's properties.

What solvents change water's boiling point?
Any solvent can; the more ions it dissipates into, the more it will change the boiling point (in general). You shouldn't expect a very large change, however. Pressure tends to affect boiling point more than solvents.
How can you change concentration?
To increase the concentration of a solution, you can decrease the amount of solvent by boiling off, or by evaporation, or you can simply add more solute. Conversely, to decrease the concentration, you can add more solvent.
How does mass change when solutes are added to solvents?
When solutes are added to a solvent, the overall mass of the solution increases because the mass of the solute is now part of the total mass of the solution. The mass of the solvent remains the same, but the combined mass of the solute and solvent will be greater than the original mass of the solvent alone.

The tendency of a solute to change the boiling point of a solvent is called boiling-point elevation. This occurs because the presence of the solute disrupts the solvent's ability to form vapor, therefore requiring more heat to reach the boiling point.
What are the effects do solutes have on a solvent when at freezing and boiling point?
the colder a liquid, the more gas it will dissolve, the hotter it is the more solid stuff like sugar it will dissolve. the sea is other wise known as the carbon sink because of the amount of carbon dioxide dissolved in it. because of climate change, the sea is getting warmer and carbon dioxide is being relised into the atmospherei hope that helps :)
