Chapter 13

Question 1

a homogeneous mixture

Answer 1

Solution

Question 2

The component that is dissolved in solvent

Answer 2

Solute

Question 3

Medium into which solutes are mixed

Answer 3

Solvent

Question 4

Usually in smaller amount

Answer 4

Solute

Question 5

Usually in greater amount (usually liquid)

Answer 5

Solvent

Question 6

Contains as much solute as can be dissolved (at specific temp)

Answer 6

Saturated solution

Question 7

Can dissolve more solute

Answer 7

Unsaturated solution

Question 8

contains more solute than is actually stable at given temp

Answer 8

Supersaturated solution

Question 9

formed by cooling saturated solution from a higher temperature (solutes typically more stable at higher temps)

Answer 9

Supersaturated solution

Question 10

Amount (mass) of solute that forms saturated solution with given mass of solvent at specific temp

Answer 10

Solubility

Question 11

used for gases and vapor pressures of solutions

Answer 11

Mole fraction

Question 12

commonly used since volumes of solutions are easy to measure (Ex: Titration, Gravimetric analysis)

Answer 12

Molarity

Question 13

Temperature independent

Answer 13

Molality

Question 14

Temperature independent and need not know molar masses

Answer 14

Percent by Mass

Question 15

Properties that depend only on the number of solute particles in the solution and not the nature of the solute

Answer 15

Colligative Properties

Question 16

May be used to find solution molarity molality, and/or a solute’s molar mass

Answer 16

Colligative Properties (non electrolyte)

Question 17

Is the percentage of dissolved molecules that separate into ions in a solution and this can be found using colligative properties

Answer 17

Percent Dissociation (ionic)

Question 18

should have complete, or 100%, dissociation, however, experimentally determined Van’t Hoff factors indicate that this is not the case

Answer 18

Strong Electrolytes

Question 19

is more complete at lower concentrations

Answer 19

Percent dissociation of a strong electrolyte
