Separation Techniques and Understanding

There are a few separation techniques worth knowing, and those are Filtration, Distillation, Chromatography, and Centrifugation. Here's how we applied these to our Separation Project!


Filtration-
    First separation project: Filtered the sand to separate calcium chloride using a wire net
    Def. to pass through or as through a filter.


Distillation-
     Neither separation project!
     Def. the purification or concentration of a substance, the obtaining of the essence or volatile properties contained init, or the separation of one substance from another, by such a process.

Chromatography-
    Second separation project: The ink was spreading out on the filter paper
    Def. separation of mixtures into their constituents by preferential adsorption by a strip of filter paper










Centrifugation-
    Neither separation project!
    Def. spinning a mixture to separate substances
