Give ONE method of separation of a mixture.?

Answer 1

Seperating a mixture? well..... I think temperature would do the trick. Such as NaCl. You vaporize the water and the salt stays behind. But the more solute you have, the higher the temperature it takes to seperate. But seperating a homogeneous mixture is virtually impossible. :) For that answer above me, you could filter, but only when the solution is a suspension which in this case, is not a suspension. So filtering would NOT work because a suspension does not mix.

Answer 2

1. Sublimation. This involves heating a solid until it passes directly from the solid phase into the
gaseous phase. The reverse process, when the vapor goes back to the solid phase without a
liquid state in between, is called condensation or deposition. Some solids which sublime are
iodine, caffeine, and paradichlorobenzene (mothballs).

2. Extraction. This uses a solvent to selectively dissolve one component of the solid mixture.
With this technique, a soluble solid can be separated from an insoluble solid.

3. Decantation. This separates a liquid from insoluble solid sediment by carefully pouring the
liquid from the solid without disturbing the solid

4. Filtration. This separates a solid from a liquid through the use of a porous material as a filter.
Paper, charcoal, or sand can serve as a filter. These materials allow the liquid to pass through
but not the solid .

5. Evaporation. This is the process of heating a mixture in order to drive off, in the form of
vapor, a volatile liquid, so as to make the remaining component dry.

Answer 3

all the answers from above are different ways to seperate mixtures depending on the compound and mixture. some mixtures however are irreversable. such as burning wood to make carbon (charcoal) you cannot bring this back to wood and certain mixtures that you mix/bond together such as certain metals, silica (glass) are irreversable

Answer 4

Shifting

Answer 5

Distillation

Answer 6

use difference of heat of vaporization...or filtering

Answer 7

filtration

Answer 8

centrifuge
