The properties that depend on the number of solute particles irrespective of their nature relative to the total number of particles present in the solution are called colligative properties.There are four colligative properties: When a pure solvent and solution are kept with a semi-permeable membrane between them then the solvent particles pass through the membrane from the solvent side to the solution side.

Properties of Ideal solutions :HMIXING = 0VMIXING = 0, Intermolecular attractive forces between the A-A and B-B are nearly equal to those between A-B.Eg. Minimum boiling azeotropeThe solutions which show a large positive deviation from Raoult’s law form minimum boiling azeotrope at a specific composition.For example, ethanol-water mixture containing approximately 95% of ethanol forms an azeotrope with boiling point 351.15 K. Solubility of a substance is its maximum amount that canbe dissolved in a specified amount of solvent.Factors affecting the solubility of a solid in liquid : Henry’s law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.The most commonly used form of Henry’s law states that “the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution”.

Minimum boiling azeotrophic solution: Solution in which components are mixed in such a composition that they start to boil at same temperature which is found to be less than the boiling point of both components.Example: ethyl alcohol and waterComposition: 95.5% and 4.5%Boiling point: 78.40C and 1000CBoiling point of solution: 78.10CThese solutions always show positive deviation because in their composition, forces of attraction become weaker and boiling point comes out to be less than expected. This is expressed as:p = KH xHere KH is the Henry’s law constant. https://byjus.com/chemistry/important-questions-class-12-chemistry When the solute undergoes dissociation in the solution. When chloroform id added to it, chloroform molecules starts to form H-bonding with acetone molecules and since H-bonding is stronger than dipole-dipole forces, so tendency of components to escape in the form of vapours decrease.

Hypertonic solution: solution which have higher osmotic pressure than others.Example: Solution having more than 0.91% NaCl is hypertonic to human blood.iii. This will maintain sufficient supply of O2 to various parts of body throughout the day.c) Tanks of scuba-divers are diluted by adding He-gas to reduce mole fraction of N2, so that during escaping from the blood, its pressure can be reduced.So, less no. Hope these notes will help you to understand the important topics and remember the key points for exam point of view. Save my name, email, and website in this browser for the next time I comment. In liquids, the dissociation of gas is controlled by Henry’s law. Required fields are marked *. Two solutions having same osmotic pressure at a given temperature are called isotonic solutions.The solution with lower concentration or lower osmotic pressure is known as “Hypotonic” with respect to more concentrated solution.The solution with higher concentration or higher osmotic pressure is known as “Hypertonic” with respect to dilute solution. Below we provided the Notes of Class 12 for Chemistry. Which one of the two gases will have the higher value of KH (Henry’s constant) and why? At a particular temperature, when more than maximum solute gets dissolved in solvent, but lifetime of such solution is very small. Hypotonic solution: solution which have lower osmotic pressure than others.Example: solution having less than 0.91% NaCl is hypotonic to human blood.Reverse OsmosisWhen pressure more than osmotic pressure is applied, then solvent will start to flow from higher concentration to lower concentration of solution through semi-permeable membrane.

Non – ideal solutions :When a solution does not obey Raoult’s law over the entire range of concentration, then it is called non-ideal solution.Solutions showing positive deviation from Raoult’s Law : Solvent-Solute(A-B) type of force is weaker than Solute-Solute(B-B) & Solvent-Solvent(A-A) forces. ∆Vmix > 0Because forces of attraction becomes weaker and so compactness between the components decrease and thus, volume increase and comes out to be more than expected.Graphical representation of non-ideal solution: So, positive deviation becomes tendency to escape in the form of vapours increase as forces are weak after mixing.2.

This phenomenon is called reverse osmosis.Application :Desalination of sea water : When pressure more than osmotic pressure is applied, pure water is squeezed out of the sea water through the membrane. These notes will provide you Ease of all the chapters study and important points to remember. Thus, it is a colligative property. Properties of a solution which depend on number of moles of solute and not on the nature of solute.More the number of moles of solute in solution, higher will be the value of colligative properties. Download Chapter Wise Notes for CBSE Class 12 Chemistry Notes Your email address will not be published. So, more of the molecules will start to escape from liquid in form of vapours by overcoming the forces of attraction. So, tendency of components to escape in the form of vapours increase.
