colligative property

(noun)

A property of solutions that is directed by the ratio of solute to solvent, regardless of the identity of the solute.

(noun)

A property of solutions that depends on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the type of chemical species present.

Examples of colligative property in the following topics:

  • Boiling Point Elevation

    • There is one category of properties that can only be applied to solutions; these are known as colligative properties.
    • Properties can be considered colligative only if they are dependent on the amount of solute present in the solution, disregarding the identity of the solute itself.
    • The elevation of the boiling point is directly dependent on the amount of solute present in the solution, but it is not based on the identity of the solute, so it is considered a colligative property.
    • The "i" factor of the equation also factors in any dissociation that the solute may undergo; since boiling point elevation is a colligative property, the number of ions present in an electrolyte affects the elevation.

    • These electrolytic solutions share the same colligative properties as chemical solutions.
    • Discuss the importance of colloidal properties in the use of medical solutions

  • Vapor Pressure of Electrolyte Solutions

    • The number of moles of dissolved particles is greater for electrolyte solutions, so there will be a greater impact on colligative properties.
    • Vapor pressure of a liquid is a colligative property.
    • The greater the number of ions, the larger the impact on colligative properties will be.

  • Freezing Point Depression

    • Freezing point depression is a colligative property observed in solutions, brought on by the introduction of solute molecules to a solvent.

  • Osmotic Pressure

    • Solutions generally have different properties than the solvent and solute molecules that compose them.
    • Some special properties of solutions are dependent solely on the amount of dissolved solute molecules, regardless of what that solute is; these properties are known as colligative properties.

  • Vapor Pressure of Nonelectrolyte Solutions

  • Molality

    • Molality is a property of a solution that indicates the moles of solute per kilogram of solvent.
    • Molality is an intensive property of solutions, and it is calculated as the moles of a solute divided by the kilograms of the solvent.
    • Molality is an intensive property, and is therefore independent of the amount being measured.
    • Calculate the molality of a solution and explain how it is a colligative property

  • Physical and Chemical Properties of Matter

    • Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity.
    • Physical properties are properties that can be measured or observed without changing the chemical nature of the substance.
    • Some examples of physical properties are:
    • Remember, the definition of a chemical property is that measuring that property must lead to a change in the substance's chemical structure.
    • Here are several examples of chemical properties:

  • Periodic Trends in Metallic Properties

    • Metallic properties tend to decrease across a period and increase down a periodic group.
    • Keep in mind that group names can give clues about the elements' metallic properties.
    • Elements with low electronegativity tend to have more metallic properties.
    • So, the metallic properties of elements tends to decrease across a period and increase down a group.
    • Families of the periodic table are often grouped by metallic properties.

  • Background and Properties

    • If these same functional groups are attached to an acyl group (RCO–) their properties are substantially changed, and they are designated as carboxylic acid derivatives.
