What Are Colligative Properties?

Compared with the pure solvent, some physical properties of the dilute solution will be changed, such as lowered vapor pressure, lowered freezing point, increased boiling point and osmotic pressure. This is a rule of change of the chemical potential with the number of components in a multi-component system. The colligative nature of a solution is only when the concentration of the solution is very dilute, and the more dilute the solution, the regularity of its collimation The stronger. Dependency has nothing to do with the nature of the solute, and is determined by the number of lysosomes.

Dilute solutions have common properties, such as the

The well-known saline solution and glucose injection are specially formulated to be 0.9% and 5% isotonic solutions in order to maintain normal osmotic pressure of red blood cells in the blood vessels of the human body and surrounding plasma; sometimes in order to deal with some severe burns caused by large areas Special patients who are dehydrated or have increased plasma moisture due to excessive sodium loss will also use hypotonic or hypertonic solutions accordingly. Osmosis also plays a very important role in biological life phenomena.

The antifreeze used in winter car radiators uses the principle of the freezing point falling.

The determination of the relative molecular mass of an unknown substance is usually done using the colligative properties of a dilute solution. The freezing point reduction method is the most commonly used and more accurate. ^[7]
