An Overview Of The Extensive Applications Of Laboratory Water
Water is the most precious, most essential compound ever created by nature. It is basically a necessary substance not only to life but also to everything else. Organic and inorganic systems rely on the presence of water and a vast number of important chemical reactions occur in the presence of water. Also, life sustaining and life giving biochemical reactions take place in the existence of this so-called universal solvent.
The human applications of water are so vast that there is no way of enumerating every usage and every application in a single article because it is going to be an extremely broad topic. Every field of human living requires water. You take a bath, wash your clothes, cook food and keep your garden alive using nothing else but water. The agricultural, medical, industrial and scientific applications of this substance are tremendous. Aside from keeping you live by bathing your cells and acting as a medium where metabolic reactions and essential cellular and systemic functions can take place and playing an important part in the regulation of body temperature, it keeps every aspect of human civilization alive.
Nevertheless, it is good noting that different applications require different types of water. While tap water may be potable enough for general drinking and cleaning purposes, industries and laboratories may need water that is purer. It so happens that pure water hardly occurs in nature. Being an effective solvent, it readily dissolves minerals, ions and other impurities. Such impurities make water less effective for various purposes. For instance, many laboratory tests require that water be purified to yield accurate results. In addition, water for biochemical experiments and tissue culture should have high degree of sterility. Thus, tap water is out of the question.
Preparations of various types of solutions like indicator solutions such as methylene blue and methyl orange utilize water that has high standards of purity. It is also crucial for standard solutions used in chemical testings to utilize water that contain extremely low, negligible traces of impurities – ions and other solutes. These impurities render the results of analytical tests inaccurate. Thus, in preparation of laboratory acids and bases, pure water is more than a necessity. The absence of solutes in the water to be used in chemical analyses would render reliable and valid results. Therefore, such water for laboratory testing needs to be free from dissolved ions that might alter results of soil testing, for instance, in which presence of metallic elements need to be assessed as accurately as possible. The presence of too much ion concentration may alter the figures yielded by the result.
Pure and deionized water is a much more aggressive solvent than ordinary tap water and, thus, it is an effective cleaning agent. A good example is the use of such water in cleaning glass wares. Ordinary water, which has a relatively high concentration of minerals, will produce stubborn stains on glass surfaces. Tap water is generally not an effective cleaning agent for glass, whether we are talking about your glass pitcher at home or chemistry glass apparatuses such as beakers, flasks, graduated cylinders, pipettes, burettes, etc. Nevertheless, with the use of purified water, stubborn dirt may be effectively removed through fast dissolution. This is due to the high degree of dissolving power of pure, demineralized water.
The process of water purification and demineralization or deionization is complex and these types of water with high degree of purity may be impractical for home use. You may be happy to have a water purifying system at home without the need for further deionization, since you are using water for general purposes. However, in chemical laboratories, hospitals, and other establishments where strict standards are followed, water needs to be at its purest and safest state as much as possible. This kind of water undergoes filtration to remove solid macro-impurities. Then the ions are removed through a process called deionization. To finally render the water safe and germ-free, it may undergo exposure to ultraviolet radiation.
