Colligative properties

Question 1

Definition

Answer 1

Changes of the behavior that are dircatly related to the consideration of particales, regardeless their chemical nature (os)

Question 2

Os M

Answer 2

The concentration of particales, calculated as moalarity multiply the number of ions.

Question 3

Vapor pressure

Answer 3

The pressure vapors (gases ) exert over a solvent .

Question 4

Vapors

Answer 4

Solvent molecules which gained enough energy to break intermolecular forces and change their phase from liquid to gas.

Question 5

Vapor pressure depression

Answer 5

A solvent with solute dissolved in it has a lower vapor pressure than the vapor pressure of the pure solvent (water)

Question 6

Boiling point

Answer 6

Constant of boiling is 0.52

Question 7

Freezing point

Answer 7

Constant of freezing point 1.86

Question 8

Boiling and freezing point

Question 9

Osmosis

Answer 9

Passage of water molecules from era of low concentration to era of high concentration.

throgh a semi perimable membrane in order to equliz concentration.

osmotic pressure is the pressure created on the Membrain by the passage of water..

Π (osmotic p) = osM*R*T

R= 0.083 ATM / 8.314 KPA

T= temperature in kelvin.
