pass through filter paper, *can’t be separated by filtration

20
Q

colloids, separate?

A

stay suspended by molecular motion of dispersing medium

21
Q

colloids, define

A

particles can’t be seen by the naked eye

22
Q

colloids, light?

A

show the Tyndall effect, scatter light

23

jello, fog, smoke

25
Q

***mixtures are categorized by ____

A

particle size

26
