Water is a polar solvent, meaning it has partial opposite charges at each end of each molecule, and so ionic substances, in which each particle is charged, and other polar substances dissolve best in water. However, to dissolve a substance, the attraction of the solvent for particles of the solute must be greater than the forces holding the solute together, so many ionic substances are not soluble in water.Know More
Two common examples of substances that dissolve in water are table salt, sodium chloride, and the common sugar sucrose. Despite their similar appearance, the two substances are very different in both composition and their inter-particle forces, with salt composed entirely of sodium and chloride ions ionically bonded to one another, and sucrose a covalent compound composed of carbon, oxygen and hydrogen, held together by the polar nature of the molecules. In both cases, the polar attraction of water molecules exceeds the inter-particle forces of the solids, and so individual particles are pulled into the solution.
It is not only solids that are soluble in water, however. Both liquids and gases can also be soluble. In these cases, solubility still depends on the polar nature of each molecule of gas. Polar gases such as ammonia are very soluble, while non-polar gases such as nitrogen are much less soluble.Learn more about Solutions & Mixtures
Water is a versatile solvent because it dissolves more substances than any other liquid. As a polar molecule, with the oxygen side having a negative charge and the hydrogen side having a positive charge, water can bind to ions and other polar molecules, dissolving them.Full Answer >
Water is a polar molecule because it possesses a negative point and a positive point in its structure as opposed to a consistent charge throughout. Some other examples of polar molecules are ammonia, sugars and hydrogen fluoride. Polar molecules are defined by having both a negative charge and a positive charge, much like that of a magnet. Molecular polarity is the cause of many chemical phenomena, such as surface tension.Full Answer >
A polar solvent is composed of molecules, such as H2O, that have a discernible asymmetry in their surface electromagnetic charge. Water molecules consist of one oxygen atom single-bonded to two hydrogen atoms that are grouped together on one side of the molecule. This concentrates a negative charge at one pole.Full Answer >
Silicone can be dissolved with a variety of solvents available online or in hardware stores. These products are sometimes called silicone eaters, and they work on both cured and freshly applied silicone.Full Answer >
