the temperature at which the solution freezes is lowered.
Solute fills the gaps in solvent so attractive forces among solvent molecules becomes reduced so further lower temperature is require to convert liquid into solid state.
Adding a solute to a solvent will reduce its freezing temperature and increase its
boiling temperature.
Antifreeze
It brings the solute and solvent rapidly into contact.
the temperature at which the solution freezes is lowered.
raise its freezing point
No, generally that would lower the freezing point, not raise it. Salty water freezes at a lower temperature than pure water. And salt can melt ice, which is the same phenomenon.
When adding a solute to a solvent, the freezing point decreases and is also known as freezing-point depression. Hence when naphthalene is added to camphor the freezing point decreases.
When any solute is dissolved into a solvent, the freezing point will always go down.
Adding a solute to a pure solvent will lower the freezing point, elevate the boiling point, and lower the vapor pressure.
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.
It brings the solute and solvent rapidly into contact.
by adding solvent, the ability of solvent molecules to escape(i.e its vapour pressure) will decrease.because the solute particles provide hinderance
the temperature at which the solution freezes is lowered.
the temperature at which the solution freezes is lowered.
The addition of solute to a solvent concentrates the overall solution. A nice example is the laundry detergent. Some (less) concentrated detergents are less viscous, while highly concentrated detergents are more viscous (greater density). Also, adding more solute to a solvent can lower the freezing point.
boiling point is increased and freezing point is decreased
