The freezing point of a solution is generally higher than the one of a pure solvent.
This is because in a solution, the solvent is in contact with more molecules (the ones of the solute plus the ones of the solvent) thus increasing the Van Der Waals forces between molecules, making it easier for them to stick together as the temperature goes down.
The molecules of the pure solvent don't interact with so many molecules, so the intermolecular forces are not as high as in solution thus making it harder for molecules to change to a solid state, lower temperatures will be needed in order to turn liquid pure solvent into a solid.

How does adding salt to water affect the temperature?
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
The presence of a nonvolatile solute will what the boiling point of a solvent?

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 are the effect of impurities on the freezing point of water?
Impurities in water lower its freezing point and raise its boiling point. This occurs because impurities disrupt the formation of ice crystals, requiring a lower temperature to overcome these disruptions and freeze the water.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
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 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.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.
What will the nonvolatile solute do to the freezing point of a solvent?
This is the property of freezing point depression and boiling point elevation. This is because of the solute absorbing the energy added to the system to heat its own molecules and so it would require more energy to boil the solvent. Likewise for freezing point depression, the molecules retain more energy.
What affects freezing point?
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
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.
How does adding salt to water affect the temperature?
It does not affect the temperature of the water, but solutes raise the boiling point and lower the freezing point.
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.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
