The pioneering paper by Bernal and Fowler dealing with the chemical physics of water appeared in 1933 (2). Water is an essential ingredient of animal and plant life crediting to its unique physical, chemical and biological properties. Water and Environment: Physical chemical properties of water. Water undergoes various types of chemical reactions. Adhesion and cohesion lead to capillary action, which is seen when the water rises up a narrow glass tube or within the stems of plants. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. One of the most important chemical properties of water is its ability to behave as both an acid (a proton donor) and a base (a proton acceptor), the characteristic property of amphoteric substances. Chemical properties Acid-base reactions. Articles include both Perspectives and original research contributions. Adhesion is another property of water. Water is adhesive to molecules capable of forming hydrogen bonds with it. List a county or region in which this method of conversion is currently in use. Describe the chemical and physical properties of seawater. Adhesiveness is a measure of water's ability to attract other types of molecules. Summative_Evaluation_-_Properties_of_Water.doc Comprehensive check on students understand when it comes to the properties of Water… Describe two different methods used to convert seawater into drinkable water. Properties_of_Water_Preassessment.doc Ideas and Suggestions for the introduction and preassessment of the Chemical and Physical properties of Water unit. Physical and Chemical Properties of Water Salt Water and Salinity Hydrothermal Vents Salt Water and Salinity Seawater contains most all elements found on Earth Most of the solutes are made of a small group of common ions Solute- the substance being dissolved by the solvent Salt Water and Salinity Six (6) ions compose over 98% of solids in seawater. Identify the benefits and potential hazards of converting seawater to drinkable water. Soda_Pop.doc This transparency master illustrates the C02/H20 chemical makeup of Soda Pop. Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. This Special Feature on the Chemical Physics of Water contains 10 articles and aims to be a representative cross-section of current frontier research in this field.
