From Wikipedia, the free encyclopedia
Gravity Filtration is a scientific way to filter out the impurities in the solutions. In the chemistry laboratory, it always used to filter out the solids from the Precipitation reaction, it always has three different filtrations( standard, vacuum and pressure). The basic logic of filtration is due to the direction of gravity is pointing to the center of the Earth. Many high school or universities has already teach the knowledge about gravity filtration to students. Lots of industry used this filtration to filter out their Industrial raw materials as initial step.
This article is belonging to the Analytical chemistry. It is a way to filter out the different chemical compounds or to filter out the impurity and then the examples in industry, laboratory and real world examples. Also it will list some operations and precautions in experiments.
