Q

always made up of solute and solvent

A

solution

17
Q

the component being dissolved; the substance exisinting in small amounts compared to solvent

A

solute

18
Q

______ determines the type of solution regardless of the solute. if it’s solid then the solution will take a solid form; goes also with liquid and gas.

A

solvent

19
Q

ability to scatter visiblelight

A

tyndall effect

20
Q

heterogeneous mixture; particles are relatively big, >1000nanometers, visible to the naked eye, particles settle at the BOTTOM

A

suspension

21
Q

process of separating the insoluble solid from the liquid component by allowing the liquid to pass through a porous material acting like a filtering agent

A

filtration

22
Q

process of separating a heavy insoluble solid from the liquid component by allowing the heavy particles remain first at the bottom; liquid is poured off slowly to the other container

A

decantation

23
Q

process that involves the use of forceps, sieves, magnets, and other tools

A

mechanical separation

24
Q

used to separate a mixture of solid and liquid by transforming the liquid component to a gas through heating

A

evaporation

25
Q

process used to separate a mixture of solid and liquid, and a mixture of liquid through evaporation and condensation to recover the liquid component.

A

distillation

26
Q

liquid formed from the condensation of the vapor

A

distillate

27
Q

catching the vapor and turning it back to its liquid state

A

distillation

28
Q

separating the components of the mixtures on the basis of the difference of the degrees to which substances are absorbed on the surface of an inert substance such as filter paper.

A

chromatography

29
Q

commonly used wherein alcohol and water act as a solvent (mobile phase) while the paper acts as a stationary phase

A

paper chromatography

30
Q

separating of a solid substance from a solution thru the means of centrifuge

A

centrifugation

31
Q

a motor device that speed sup the settling of the precipitate using centrifugal or rotating motion

A

centrifuge
