Front 2

solution

Back 2

homogeneous mixture of two or more substances in a single phase

Front 3

Front 4

solute

Back 4

the substnace being dissolved in a solution / least of

Front 5

suspension

Back 5

heterogeneous mixture with larger particles which settles unless constantly agitated

Front 6

colloids

Back 6

made from particles between the size of those in solutions and those in suspensions

Front 7

tyndall effect

Back 7

when light is scattered by colloidal particals dispersed in a transparent medium

Front 8

brownian motion

Back 8

the rapid, random motion of particles due to collision s of rapidly moving molecules

Front 9

electrolyte

Back 9

substance that dissolves in water to give a solution that conducts electric current

Front 10

nonelectrolyte

Back 10

substance that dissolves in water to give a solution that does not conduct an electric current

Front 11

solution equilibrium

Back 11

the physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates

Front 12

saturated solution

Back 12

solution that contains the maximum amount of dissoved solute

Front 13

unsaturated solution

Back 13

solution that contains less than the maximum amount of solute

Front 14

supersaturated solution

Back 14

solution that contains more dissolved solute than a saturated solution under the same conditions

Front 15

seeding

Back 15

dropping a small crystal of the solute in a supersaturated solution, causing the rapid formation of crystals

Front 16

solubility

Back 16

amount of a substance required to form a saturated solution with a specific amount of solvent at a specified temperature

Front 17

hydration

Back 17

solution process with water as the solvent

Front 18

solvation

Back 18

solution process when water isn't the solvent

Front 19

immiscible

Back 19

liquids that are not soluble in each other

Front 20

miscible

Back 20

liquids that dissolve freely in one another in any proportion-

Front 21

henry's law

Back 21

solubility of a gas in a liquid is directly proportional to the partial pressure of that gas on the surface of the liquid

Front 22

effervescence

Back 22

the rapid escape of a gas from a liquid in which it is dissolved

Front 23

solvated

Back 23

solute partical that is surrounded by solvent molecules

Front 24
