How does the boiling point of a solvent change when a solutes is dissolved in?

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.

∙ 11y agothe boiling point of a solvent change with the addition of solutes because every substance has its own specific biling point. So, when any impurities are dissolved in a solvent then each of the solute will boil at its own boiling point. so, the boiling point of the solvent gets affected.

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.
Is iodine dissolves in alcohol a chemical or physical change?
Dissolving (as such) of solutes in a solvent is physical.
What is meant by the term thermochromic?
this is the dramatic, reversible colour change that occurs when a material is melted or dissolved in a solvent, it is a phase change not a temperature effect despite its name.
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.
Why you need to heat the solution in order to prepare supersaturated solution?
Effect of heat would be the solvent will be dissolved fast and the temperature changes contribute to the change of the effect of the supersaturated solution.
How adding solute changes the properties of a solvent?
Solutes raise and lower the boiling points of solvents. :)

Is dissolution of sulphar in carbon disulfide a chemical change?
No, dissolving solutes in a solvent is always a physical change!
Is iodine dissolves in alcohol a chemical or physical change?
Dissolving (as such) of solutes in a solvent is physical.
How does mass change when solutes are added to solvents?
The mass of the whole doesn't change, it's simply the sum of the mass of the solute and the mass of the solvent.
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 :)

What are physical changes of antifreeze when dissolved in water?
will change the boiling and freezing point of the water
What are two ways in which you change the concentration of a solution?
Evaporate the solvent; crystallize the dissolved material (by various techniques).
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
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.
Whats a solute and a solvent?
Solute = the substance dissolved in a given solution. Solvent = a. the process by which a gas, liquid, or solid is dispersed homogeneously in a gas, liquid, or solid without chemical change. b. such a substance, as dissolved sugar or salt in solution. c. a homogeneous, molecular mixture of two or more substances.
