Definition of Filtration in Chemistry

Definition of Filtration in ChemistryOne of the key skills that a student will need to have as a chemistry major is the ability to define filtration in chemistry. The ability to define what filtration means is extremely important in the life of any chemist. The term 'filtering' is used by chemists to describe the process by which molecules and other solids are passed through a filter or separator.If you study the basic term itself, then you will be able to gain a very good understanding of what the word means. Filters are used to separate different types of materials in order to prevent impurities from getting into the product that it is used in. It is this first definition that people often use when referring to filtering in chemistry. A little further investigation will also reveal that it is very important to know what the exact term means before using it as an example of filtration in chemistry.A filtration system is one that allows for a clear separation of materials. Filters al low for a uniform distribution of substances are separated from each other by size, shape, and density. The most commonly used filtration systems are filters for water, and such as the paper towel. They allow for the removal of impurities such as bacteria and parasites.Filtering in chemistry can be further subdivided into the following: passivation, blockage, and physical. Most people think of filtration in chemistry when they are taught the term 'filtering'. What they may not realize is that there are many other types of filtration methods that are used in chemical analysis.Filtering in chemistry involves the three processes listed above. The first method is the application of liquid or solids through an opening to be separated by mechanical or physical means. Blockage involves using a solute (a solid, liquid, or gas) so that it cannot pass through the filter.The second process is called biological process or biological filtering. This method uses the biological process in which it involves chemicals that a living organism has been exposed to. In the early 1900's, it was discovered that certain liquids were bad for an organism and some changes were made to these liquids to discourage the harmful effects that they had on an organism.The third analytical process is a mass spectrometer. A mass spectrometer utilizes a sample of substance to view the amount of chemical components within the sample. It is used to determine if certain compounds are present in a sample of substance and if so, how big or small the compounds are.
