What effect does adding a solute have on the boiling of solution?
The solution freezes at a lower temperature and boils at a higher temperature.
Explain why the vapor pressure boiling point and freezing point of an aqueous solution if a nonvolatile solute are not the same as those of the pure solvent?
The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.
Why would the boiling point of a solution be higher than that of a pure solvent?
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.
What will adding solute to pure solvents cause?
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.
What is the effect of the boiling point and freezing point of a solution with electrolytes is caused?
it's a colligative property of solutions... when you add a higher boiling substance to a solution the boiling point increases and when you add anything that interferes with the intramolecular forces holding the solution together the freezing point decreases.
What effect does adding a solute have on the boiling of solution?
The solution freezes at a lower temperature and boils at a higher temperature.
How do you obtain a pure solvent from a solution by distillation?
To obtain a pure solvent from a solution by distillation, heat the solution in a distillation apparatus. The solvent will evaporate first due to its lower boiling point, leaving behind the solute. The vapor is then condensed back into liquid form, resulting in a pure solvent separate from the solute.

Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.

Which solution contains a higher concentration of solvent that the solution it is being compared with?
The solution with the higher concentration of solvent compared to another solution would be the one with a lower concentration of solute. The solvent concentration is higher in the solution where the solute concentration is lower.

Does adding a solute to a solvent raise the boiling point?
Yes, adding a solute to a solvent raises the boiling point of the solution. This is known as boiling point elevation and occurs because the presence of solute particles interferes with the solvent's ability to escape as vapor, requiring higher temperatures to achieve boiling.
What lowers the freezing point and raises the boiling point?
Adding solutes, such as salt or sugar, to a solvent can lower the freezing point and raise the boiling point. This phenomenon is known as freezing point depression and boiling point elevation, respectively. The presence of solutes disrupts the normal crystal structure in the solvent, requiring lower temperatures to freeze and higher temperatures to boil.
What 2 solute molecules mixed with the solvent molecules in a solution cause the freezing point of a solution to be than it is for an equal volume of pure?
Adding solute molecules such as salt or sugar to a solvent like water will lower the freezing point of the solution compared to the pure solvent. This occurs because the presence of these solute molecules disrupts the regular arrangement of solvent molecules, making it more difficult for the solvent to freeze.
At what temperature must a solution be to freeze, in comparison to a pure solvent?
A solution must be at a lower temperature than a pure solvent to freeze.
