colligative properties examples in chemistry
What are colligative properties?
These colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. This small set of properties is of central importance to many natural phenomena and technological applications, as will be described in this module.
What are the ligative properties of a solvent?
Colligative properties include vapor pressure, boiling point, freezing point, and osmotic pressure. The addition of a nonvolatile solute (one without a measurable vapor pressure) decreases the vapor pressure of the solvent.
When should the equations for colligative properties be applied?
In practice, this means the equations for colligative properties should only be applied to dilute real solutions when a nonvolatile solute is dissolved in a volatile liquid solvent. For any given solute to solvent mass ratio, any colligative property is inversely proportional to the molar mass of the solute.
Are vapor pressure and osmotic pressure colligative properties?
As we will see, the vapor pressure and osmotic pressure of solutions are also colligative properties. When we determine the number of particles in a solution, it is important to remember that not all solutions with the same molarity contain the same concentration of solute particles.
How Colligative Properties Work
Dissolving a solute in a solvent introduces extra particles between solvent molecules. This reduces the concentration of the solvent per unit of volume, essentially diluting the solvent. The effect depends on how many extra particles there are, not their chemical identity. For example, dissolving sodium chloride (NaCl) yields two particles (one sod
The 4 Colligative Properties
Freezing Point Depression Freezing points of solutions are lower than freezing points of pure solvents. The depression of the freezing point is directly proportional to solute molality. Dissolving sugar, salt, alcohol, or any chemical in water lowers the freezing point of the water. Examples of freezing point depression include sprinkling salt on ice to melt it and chilling vodka in a freezer without freezing it. The effect works in other solvents besides water, but the amount of the temperature change varies by solve
Ostwalt and The History of Colligative Properties
Chemist and philosopher Friedrich Wilhelm Ostwald introduced the concept of colligative properties in 1891. The word “colligative” comes from the Latin word colligatus(“bound together”), referring to the way solvent properties are bound to solute concentration in a solution. Ostwald actually proposed three categories of solute properties: 1. Collig
