Answer 1

Answer:

1. colligative properties are those properties which depend on the number of partical ( atom, molecules) which does not depend on the nature of partical

2. mole fraction are fraction the number of moles of particals present in a total solution

3. van" t hoff charls law the contraction remaining constant the osmotic pressure of dilute solution is directly proportional to absolute temperature of solution

4. isotonic solution it refer two solution having the same osmotic pressure accor a semipermeable membrane this states a free movement of water across the membrane without changing a contraction of the solute

5. eullioscopic constant the ratio of elevation of boiling point of a solvent caused by dissolving a solute to molality of solution taken at extremely low concentration

it also known as molal elevation of boiling point

6. solution= solute +solvent
