What do you mean by Colligative?
colligative property, in chemistry, any property of a substance that depends on, or varies according to, the number of particles (molecules or atoms) present but does not depend on the nature of the particles.
What is meant by Colligative effect?
Colligative Properties. Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
What are the 4 colligative properties?
There are four colligative properties: vapor pressure lowering, boiling point ele- vation, freezing point depression, and osmotic pressure.
Which is the colligative property?
Solutions’ colligative properties are properties that depend on the concentration of molecules or ions of the solute, but not on the identity of the solute. Colligative properties include lowering of vapour pressure, boiling point elevation, depression of the freezing point, and osmotic pressure.
What are colligative properties 12?
Colligative properties are properties of a solution which depend only on the number of particles like ions or molecules of the solute in a definite amount of the solvent but not on the nature of the solute.
What colligative properties abnormal?
Answer: Abnormal colligative property: When the experimentally measured colligative property of a solution is different from that calculated theoretically by the van’t Hoff equation or by the laws of osmosis, then the solution is said to have abnormal colligative property.
How colligative properties are commonly used in everyday life?
Freezing point depression is one colligative property we use in everyday life. Many antifreezes used in automobile radiators use solutions that have a lower freezing point than normal so that automobile engines can operate at subfreezing temperatures.
What are three examples of colligative properties?
Examples of colligative properties include vapor pressure lowering, freezing point depression, osmotic pressure, and boiling point elevation.
How many types of colligative properties are there?
four colligative properties
Ans: The four colligative properties are- Relative lowering of vapour pressure, the elevation of boiling point, depression in freezing point, osmotic pressure.
What is a cause of abnormal colligative properties?
When the dissolved solute undergoes a molecular change like dissociation or association in the solution, it causes abnormal colligative properties.
What are colligative properties give the reasons for abnormal colligative properties?
The colligative property depends on the number of solute particles in the solution but it is independent of their nature, Abnormal values of them arise when the dissolved solute undergoes a molecular change like dissociation or association in the solution.
