Lesson 7: Colligative Properties

Question 1

refers to the property of the solution that depends on the number of solute particles present

Answer 1

Colligative Properties

Question 2

What are the 2 colligative properties?

Answer 2

1. Boiling Point Elevation
2. Freezing Point Depression

Question 3

the solution of the nonvolatile nonelectrolyte solutes (solute does not have a vapor pressure of its own) boils at higher temperature than other solvents

Answer 3

Boiling point elevation

Question 4

directly proportional to molal concentration of the solution

Answer 4

Boiling point elevation

Question 5

△Tb=Kb*m

Answer 5

Boiling point elevation

Question 6

pure water freezes at 0°C but when added a certain amount of any soluble substance will lower its freezing point

Answer 6

freezing point depression

Question 7

freezing point of solution is always (lower or higher) than the freezing point of the pure solvent

Answer 7

lower freezing point

Question 8

varies directly with molal concentration of the solution

Answer 8

freezing point depression

Question 9

△Tf=Kf*m

Answer 9

Freezing point depression

Question 10

similar analysis to solutions with nonelectrolyte except that the dissociation of the electrolytic solute is considered and incorporated

Answer 10

Solutions with electrolytes

Question 11

What is i, where it represents as an equivalent to the number of ions in one formula unit of an electrolytes solute?

Answer 11

Van’t Hoff factor

Question 12

△Tb=i (m)(Kb), △Tf=i (m) (Kf)

Answer 12

Solutions with electrolytes
