Environmental Pollution Series B: 87- 95. Water - Water - Physical properties: Water has several important physical properties. Although these properties are familiar because of the omnipresence of water, most of the physical properties of water are quite atypical. As a hard base, water reacts readily with organic carbocations; for example in a hydration reaction, a hydroxyl group (OH−) and an acidic proton are added to the two carbon atoms bonded together in the carbon-carbon double bond, resulting in an alcohol. The mean concentration of physicochemical parameters and trace metals is given in Table 1. PHYSICOCHEMICAL PROPERTIES (Recommendations approved 1977) EDITOR: K.N. Some of these properties may be affected by processing such as thermal processing and acid/alkali processing as the processing tends to denature the protein, resulting in altered structure of protein. However, little is known about functional properties of this starch. The structure and properties of water are integral to the existence and evolution of life on any number of levels. 2014).
