Making extensive use of polymer chemistry concepts, it has recently been claimed that water is a good solvent for the denatured state of globular proteins [J.Mol.Biol. 432 (2020) 2882]. Here, I discuss how overinterpretation of classical polymer chemistry should be avoided and how recent ideas...
water as polar solvent (why water is good transporting medium?) Since water is a polar molecule and has hydrogen bond, ionic substance like sodiumchloridewill dissolve in it. Polar molecules can also dissolve in it. Water also carries other non soluble substance like starch. As a result, most...
"Arthur Guyton 'sTextbook of Medical Physiologystates that "the total amount of water in a man of average weight (70 kilograms) is approximately 40 litres, averaging 57 percent of his total body weight. In a newborn infant, this may be as high as 79 percent of the body weight, but it...
This is good for hydraulic mechanisms in living organisms Water has a high surface tension Organisms can live on the surface of water Water has a lower density when frozen Ice forms a habitat on top of the water REACTANT LOADS OF chemical reactions transport liquid and a solvent -- transport...
Water is known as theuniversal solvent. Here is an explanation of why water is called the universal solvent and what properties make it good at dissolving other substances. Chemistry Makes Water A Great Solvent Water is called the universal solvent because more substances dissolve in water than in...
Water is an excellent solvent for organic chemistry and microwave heating offers a very efficient way of heating reaction mixtures. In this article, by focusing on the Suzuki reaction, it is shown how these two methods, used alone or together, can impact modern synthetic chemistry, making reactio...
Water has several unique characteristics that make it an extremely valuable resource. Some such properties of water are listed below.Water is a very good solvent – it has the ability to dissolve many substances.The boiling point and freezing point of water m...
The meaning of WATER is the liquid that descends from the clouds as rain, forms streams, lakes, and seas, and is a major constituent of all living matter and that when pure is an odorless, tasteless, very slightly compressible liquid oxide of hydrogen H2
Water activity, Aw is defined as the ratio of the water pressure of the food to the vapor pressure of pure water at the same temperature. 参考译文: 为了解释水对食品品质的影响,有一个指标参数既能反映含水量也能反应食品中水的需求量。这个参数就是水分活度。
1. Explain why water is such a good solvent for so many different solutes? 2. Why should solutes be added to water rather than water added to solutes ? Explain why water is such a good solvent for so many different solutes and describe the similarities in the dissolving process for ionic...
