Common table salt is odorless, white and cubic in structure. It is hygroscopic, has a melting point of 1,472 degrees Fahrenheit, a boiling point of 2,669 degrees Fahrenheit and a density of 2.165 grams per cubic centimeter. Salt is used as a food additive, an industrial additive and a de-icing agent.Know More
Salt is an ionic compound consisting of sodium and chloride in a face-centered-cubic lattice structure. Salt contains equal portions of chlorine and sodium. Bulk salt crystals are translucent and cubic in shape. Pure salt is white, although impurities may give it a blue or purple tinge.
Salt has a high water solubility of 359 grams per liter. Salt in water solutions can be made to recrystallize as dehydrate sodium chloride, where each sodium chloride molecule is weakly bonded to two water molecules. Adding salt to water changes its physical properties. A salt and water solution has a lower freezing point than just water. As the amount of salt added increases, the freezing point correspondingly decreases until the solubility limit.
Salt used for culinary applications is usually refined to between 97 and 99 percent purity. Additives to table salt include anticaking agents, such as sodium aluminosilicate or magnesium carbonate, which make the salt flow more freely.Learn more about Atoms & Molecules
Some of the properties of metals are thermal and electrical conductivity, malleability, fusibility and the ability to be stretched thinly, such as in the making of copper wire. Most metals are shiny and hard. They are also versatile in the way in which their properties can be controlled or altered to suit various industrial and technological needs.Full Answer >
Properties of magnesium include its atomic number of 12, atomic mass of 24.30 grams per mole and a density of 1.74 grams per cubic centimeter. It has a boiling point of 1,994 degrees Fahrenheit and a melting point of 1,202 degrees Fahrenheit.Full Answer >
Helium is a gas that is colorless, odorless and does not react with other elements under normal circumstances. Scientists classify helium as a noble gas.Full Answer >
Silver's properties include that its thermal and electrical conductivity are higher than any other metal. The only reason it isn't more widespread in electrical systems is that it is too expensive compared to copper and tarnishes more quickly than gold. However, it is used in high frequency radio engineering, and some stereo-system owners believe silver wire produces better sound quality.Full Answer >
