Chapter 13/14 Vocabulary

Question 0

Define miscible

Answer 0

Two or more mutually soluble liquids. Ex: vinegar and water

Question 1

Define effervescence

Answer 1

The escape of gas from a liquid in which it is dissolved (the hiss when you open a pop)

Question 2

Define Immiscible

Answer 2

Two or more mutually insoluble liquids. Ex: oil and water

Question 3

Define unsaturated solution

Answer 3

One that is still able to dissolve more solute for a given T and V

Question 4

Define Supersaturated solution

Answer 4

One that has been forced to dissolve more then it should for a given T and V

Question 5

Define solubility

Answer 5

Amount of solute that will form a saturated solution, given t&v of solvent

Question 6

Define saturated solution

Answer 6

One that has dissolved the maximum

Question 7

Define increased surface area

Answer 7

Achieved by crushing or grinding solute inTo fine particles

Question 8

Define agitation

Answer 8

Stirring or shaking the solute/ solvent. Allows fresh solvent to contact undissolved solute rate increased

Question 9

Define the change of temperature

Answer 9

Increased T will make collisions between solute and solvent to be more energetic and frequent. Rate increased but note some solutes dissolve better in cold solvents

Question 10

Define electrolytes

Answer 10

Dissolve in solutions to yield ions and will support electric currents; usually ionic ally bonded

Question 11

Define non electrolytes

Answer 11

Dissolve in solutions but will not support electric current, usually covalently bonded

Question 12

Define Tyndall effect

Answer 12

Used to determine the difference between colloids and true solutions

Question 13

Define suspension

Answer 13

When particles in a solid are too large to dissolve and they settle (heterogeneous) particle size is 1000nm+

Question 14

Define colloids

Answer 14

When particles in a solvent are too large to dissolve but too small to settle out. Particle size 1-1000nm+

Question 15

Define heterogenous mixture

Answer 15

Two clearly different components (bunch of things mixed together)

Question 16

Define homogenous mixture

Answer 16

Two or more substances in a single phase with uniform composition (koollaid) ( saltwater)

Question 17

Define solution

Answer 17

A homogenous mix of two or more substances is a single phase

Question 18

Define solvent

Answer 18

Present in greater amount; does the dissolving

Question 19

Define solute

Answer 19

Present in lesser amount; that which is dissolved

Question 20

Answer 30

Dissolving fats, oils and greases

Question 31

Dissociation

Answer 31

Separation of ions in solution

Question 32

Henry’s law
