The components of a mixture can be separated by simple physical methods such as filtration, sublimation, evaporation, or by using magnets, solvents, etc. for example, by using a magnet you can separate iron filings from the mixture of iron filings and sulphur. Similarly, you can remove water...
A mixture qualifies as a colloid when its particles are larger than those in a solution but small enough to remain suspended indefinitely without settling. 10 Can colloids be separated by conventional filtration? Conventional filtration typically cannot separate colloidal particles due to their small siz...
If you mix oil and water together, the mixture contains two liquid phases because the oil will float on top of the water because of the oil's lower density. They are not going to mix together like alcohol and water do. You can see the boundary between them and in fact, they are mech...
Filtrate is the liquid that has passed through a filter, removing solid impurities. Residue is the solid material left behind in the filter after the filtration process.
When separating a mixture by standard column chromatography, why is it better to change from a less-polar solvent to a more-polar solvent, rather than the reverse? What is hydrophobic exclusion and what force drives it? What would be the effect if the sample that has to be purified by col...
Decantation is a process used to separate a mixture. It usually involves removing the liquid portion of a substance while leaving behind the sediment. This process is used in a variety of instances. Red wine is a common example of a substance that is decanted. Wastewater may also be ...
4.What can be inferred from the lecture about the process of distillation? A. It cannot be used if a mixture has variable properties. B. It can be used to separate the components of homogeneous mixtures. C. It is used to change heterogeneous mixtures Into homogeneous mixtures. D. It is...
and the organic layer was separated and Dry over Na2SO4, remove the drying agent by filtration and concentrate the filtrate by rotary evaporation. To the residue is added CH2Cl2 (40 ml) and the reaction mixture is acidified with 1M active hydrochloric acid until pH=1. The mixture was ...

Blood is slightly denser and is approximately three to four times more viscous than water. Blood consists of cells that are suspended in a liquid. As with othersuspensions, the components of blood can be separated by filtration. However, the most common method of separating blood is tocentrifuge...
