The chemical make-up of sodium chloride is NaCl. Sodium Chloride is composed of is composed of a negatively charged chloride ion (Cl) and a positively charged sodium ion (Na). So I believe that when sodium chloride is dissolved in water the two ions that compose the sodium chloride should separate, and support an electrical current that would be supplied by a nine-volt battery
Solutions are evenly distributed mixtures of at least two substances, but they are not limited to just two substances. The most abundant substance in a solution is called the solvent but the solvent is not always the most abundant. The less abundant substances are called solutes. The solvent is always a liquid and in most cases the solvent is water but it is not limited to water. Alcohol is also a common solvent. Solutes are usually solid substances, and they are not limited to only being solids, for example another liquid can be the solute.
Some liquids can dissolve in each other in any proportion; others have limits. If a solute added to a solution above a certain amount will not dissolve, the solution is called saturated. For most substances, solubility increases with increasing temperature of the solvent. In general, molecules that are structurally similar to the molecules of the solvent have the highest solubility. When a solute is added to a solvent, several physical properties of the solvent change. Its boiling point rises and its freezing point lowers with increasing concentrations of solute.
Solutions are similar to other types of mixtures known as colloids and suspensions. Colloids are mixtures of tiny particles of one substance, called the dispersed phase, suspended in another substance, called the dispersion medium. The particles are so small that they remain in suspension indefinitely, unaffected by gravity. Both the dispersed phase and the dispersion medium may be solid, liquid, or gaseous, although the dispersal of one gas in another is not known as colloidal dispersion.
An aerosol is a colloidal dispersion of either a solid or a liquid in a gas. An emulsion is a colloidal dispersion of a liquid in another liquid. A sol is a colloidal dispersion of solid particles in a liquid. A gel is a sol in which the suspended particles are organized in a loose but definite three-dimensional arrangement, giving some rigidity and elasticity to the mixture.
Because of their small size, colloidal particles can pass through ordinary filters, but not through the extremely fine openings in a semi-permeable membrane, such as parchment. Although individual colloidal particles are too small to be seen with an ordinary microscope, they can be made visible by means of an ultramicroscopic or dark-field microscope. The particles are directly visible in an electron microscope.
Solutions are not considered to be solutions ...
When a stone flake is used in specific applications, such as sawing or whittling, distinct wear patterns are formed. In addition, unique patterns are also formed by the surface on which the tool is used. Wood, meat, hide, and bone all leave dissimilar scars on a lithic device. Modern archaeologists have devised a method, called use-wear analysis...
We have learned much about the Woolly Mammoth almost more than any other dinosaur that has been identified. Due to the fact that the Woolly Mammoth so closely resembles today's elephants, care for them would most probably require most of the same factors to keep it alive. Since the Woolly Mammoth has been extinct for 4000 years, it is difficult t...
Physics 009 Professor Arns The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices h...
can be found in the SE sky in autumn, especially October. A dark night is especially helpful because many faint stars make up . This will help to make the fainter stars stand out because its hard enough to see a shape in . Up and to the west of , pegasus can be found. Down and to the east of aquarius, capricorn can be found. portrays a man or b...
have been witnessed ever since man has been speculating about objects in the nighttime sky and appear in records from the beginning of recorded civilization (Schweighauser 20). are made up of four distinct features. The first is the nucleus. The nucleus is made up of frozen gases, mostly water vapor with lesser amounts of carbon dioxide and ca...
