Chem Vocab #1

Question 1

solution

Answer 1

A mixture that forms when one substance dissolves another

Question 2

saturated

Answer 2

Containing the highest amount of substance; has been dissolved

Question 3

unsaturated

Answer 3

A solution that contains less than the maximum amount of dissolved solute in a concentration.

Question 4

supersaturated

Answer 4

meta-stable solutions in which there is more solute dissolved than the theoretical maximum on a solubility chart

Question 5

concentration

Answer 5

A measurement of how much solute exists within a certain volume of solvent

Question 6

molarity

Answer 6

number of moles of solute dissolved in one liter of solution

Question 7

colligative properties

Answer 7

properties that depend on the concentration of solute particles but not on their identity

Question 8

boiling point elevation

Answer 8

the temperature difference between a solution’s boiling point and a pure solvent’s boiling point

Question 9

freezing point depression

Answer 9

the difference in temperature between its freezing point and the freezing point of its pure solvent

Question 10

solubility

Answer 10

the amount of solute that dissolves in a given quantity of a solvent at a specified temperature and pressure to produce a saturated solution

Question 11

solute

Answer 11

the substance which is being dissovled

Question 12

solvent

Answer 12

substance in which the solute is dissolved

Question 13

solution equilibrium

Answer 13

rate of dissolving= the rate of crystallization

Question 14

equilibrium

Answer 14

state where reactants and products reach a balance; rate of forward equals rate of the reverse

Question 15

equilibrium constant

Answer 15

the ratio of product concentrations to reactant concentrations at equilibrium; K

Question 16

equilibrium expression

Answer 16

equal to the concentration of each product raised to its coefficient in a balanced equation and multiplied together

Question 17

Le Chatlier’s principle

Answer 17

an equilibrium subjected to a stress will shift to relieve the stress

Question 18

dilute

Answer 18

make (a liquid) less concentrated; reduce in strength; Ex. dilute the influence of the president

Question 19

concentrated

Answer 19

Describes a solution that has a relatively large amount of dissolved solute

Question 20

reversible reaction

Answer 20

a chemical reaction in which the products re-form the original reactants

Question 21

dissolving

Answer 21

The process of mixing a solute in a solvent to produce a homogeneous mixture

Question 22

crystallization

Answer 22

The process by which atoms are arranged to form a material with a crystal structure

Question 23

products

Answer 23

the elements or compounds produced by a chemical reaction

Question 24

reactants

Answer 24

the elements or compounds that enter into a chemical reaction
