Pretty Color Lab! Chromatography!

Chromatography=Filtration+Distillation+Centrifugation

              So hear is yet another separation post, in which we used chromatography. This one was way more fun. Each of us colored a design on a water filter paper, then poked a whole in the center and inserted a rolled up piece of a paper towel within the hole. Each end had part of the paper towel sticking out. We then set the paper in a little tray of water, being sure that the paper towel was all that was touching the water, not the paper itself. The paper towel acted both as a handle and an absorption method. From this point we let the paper and paper towel sit, and let science do the talking from there.

We Waited...

And Waited... 

Then Finally This Was The End Result, Our Chromatograph Lab Was Complete!!!

Chromatography happens to be in many situations that we have been doing within chemistry. Within this  lab we used chromatography to separate the colors within the markers in which we used. Filtration happens to be another form of separation. When using filtration a mixture is being separated whether they are different particles being separated or different densities of the color spectrum being separated. Filtration is basically when a filter is used to separate mixtures or materials.

Distillation is yet another form of separation. This is a form that is widely used in chemistry activities when separating mixtures based on differences in the conditions required to change the phase of components of certain mixtures. To separate mixtures that include liquids, one may heat the liquid in order to force elements that may have different boiling points out of the space. This can be conducted by transferring the liquid into a gas. From this phase the gas may be condensed back into a liquid form after it has been recollected. This process can be repeated in order to achieve a more purified product, which is called a double distillation. Double distillations are most commonly used within liquids but the reverse side of their process can be applied to gases as well, by liquifying gases by the changes in temperatures that they endure.

Centrifugation is a process in which it involves the use of centrifugal forces. These forces separate the mixtures within the tubes that are placed within side the machine. The basic act of this machine is the effect of gravity on the particles within a suspension state that cause them to split and separate due to the masses, density, and weight of each of the materials present within the mixture.
