Most solutions have a HIGHER boiling point than the pure solvent. A solution with a lower boiling point than the solvent has formed an azeotrope.
The solution freezes at a lower temperature and boils at a higher temperature.
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.
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.
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.
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.
The solution freezes at a lower temperature and boils at a higher temperature.
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.

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.

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.

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.
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.
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.
A solution must be at a lower temperature than a pure solvent to freeze.
