Water is a simple compound with a set of unique properties that are essential for life. In the hydrologic cycle, water is transferred between the land surface, the ocean, and the atmosphere. The sight of ice floating on water is commonplace, but it shows the unusual chemical behaviour of water, which is less dense as a solid than in its liquid phase. It is an oxidizing agent, able to transfer oxygen to a variety of substrates, while gaining one or more electrons via oxidation-reduction (). The fact that ice floats on water is exceedingly important in the natural world, because the ice that forms on ponds and lakes in cold areas of the world acts as an insulating barrier that protects the aquatic life below. Many people feels that this is an unacceptable method of softening water as many fish that prefer soft water don’t like sodium either. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. One of the ACD/Index names for water is, indeed, hydroxyl, although it is not specified as an acid. Because an oxygen atom has a greater electronegativity than a hydrogen atom, the O―H bonds in the water molecule are polar, with the oxygen bearing a partial negative charge (δ−) and the hydrogens having a partial positive charge (δ+). chem. 6 years ago. The first part of a hydrate's name—sodium carbonate in this example—is the name of the anhydrous compound. What is this information? Water, H 2 O. It's important to remember that common names are inaccurate and vary from one place and time to another.
