Answer:- Their are some properties of solution which decreases the vapour pressure of solution called colligative properties. ★ It depends only  upon the no. of solute particle present in the solution. Some example of colligative properties are: -   1. Relative lowering of vapour pressure   2. Elevation of boiling point   3. Depression in freezing point   4. Osmotic pressure of the solution

Answer:- If a solution in which no more solute can be dissolved at a fixed temperature & pressure then that solution is called saturated solution.

Answer:- The solutions which obey Raoult's law over the entire range of their Vapourisation and condensation are called ideal solution. It means no heat is absorbed or evolved when the processes occur and Volume of the solution would be equal to the sum of volumes of the two component after the processes.

Answer:- Boiling point of a liquid is defined as the temperature at which Vapour pressure of that liquid is equal to atmospheric pressure.

Answer:- The solution which have less amount of solute(that means more solvent) is called hypotonic solution.

Answer:- The solution which have more no. of solute is called hypertonic solution.

Answer:- Two solutions have same osmotic pressure at a given temperature is known as isotonic solution.When such solutions are separated by semipermeable membrane no osmosis occurs between them.

Answer:-   Vapour pressure • pressure exercted by Vapour of the liquid (or solid) on their Piston  which closed them in a vessel is called their Vapour pressure. Partial pressure:- • The pressure exercted by each gas in a gas mixture is called partial pressure of that gas.      

Answer:- Molality of a solute is defined as the no. of moles of that solute per kilogram(Kg)of the solvent.I.e Molality=moles of solute/mass of solvent in Kg .

Answer:- Molarity of a solute is  defined as the no. of moles of that solute dissolved in one litre of solution.  I.e Molarity=No. Of moles/volume

Answer:- Solubility of a substance is it's maximum amount that can be dissolved in a specified amount of solvent at a specified temperature.It depends upon the nature of solute and solvent as well as temperature and pressure.

Answer:- If any solution have only two components (i.e one solute & one solvent)then that solution is known as binary solution.

Answer:- The component that is present in largest quantity in solution is called solvent.solvent determines the physical state in which solution exists.

Answer:- The process in which solvent molecules flow from pure solvent(solution have less amount of solute)side to solution(have more solute) side through a semi permeable membrane (SPM) is called osmosis. I.e * The flow will continue till the equilibrium is attained. The flow of the solvent from its side to solution side through a semi permeable membrane can be stopped if some extra pressure is applaid on the solvent from solution side.The pressure that just stops the flow of solvent is called osmotic pressure.
