Answer 11

It is defined as the number of parts (by weight or volume) of a solute per million parts (by weight or volume) of the solution

Question 12

Conjugate solutions

Answer 12

Each liquid layer is a saturated solution of the other liquid

Question 13

Critical solution temperature or Hoover consulate temperature

Answer 13

He temperature of 65.9 degree Celsius at which two conjugate solutions merge into one another

Question 14

Raoults law

Answer 14

The vapor pressure of a solvent above a solution is equal to the product of the vapor pressure of pure solvent and mole fraction of solvent in solution.

The lowering of vapor pressure is directly proportional to the mole fraction of solute

Answer 16

Those mixtures which distill with a change in composition

Question 17

Azeotropic mixtures

Answer 17

Those mixtures which boil at constant temperature and distill over without change in composition at any temperature like a pure chemical compound.

Question 18

Solubility

Answer 18

Concentration of the solute in the solution when it is in equilibrium with the solid substance at a particular temperature

Question 19

Freezing point

Answer 19

The temperature at which its solids and liquids have the same vapor pressures

Question 20

Heat of solution

Answer 20

The amount of heat absorbed or released when a substance forms a solution (one mole of a substance is dissolved in a specific number of moles of solvent at given temperature)

Question 21

Hydration

Answer 21

The process in which water molecules surround and interact with solute ions or molecules is called hydration.

Question 22

Hydrate

Answer 22

Crystalline substances which contain chemically combined water in definite proportions

Question 23

Water of crystallization/hydration

Answer 23

Those water molecules which combine with substances as they are crystallized from aqueous solutions
