Rock-salt = sodium chloride

As was discussed in Chapter 7, there are numerous solids that can exist in more than one form. It is frequently the case that high pressure is sufficient inducement for the structure to change. An example of this type of behavior is seen in KC1, which has the sodium chloride (rock salt) structure at ambient pressure, but is converted to the cesium chloride structure at high pressure. Other examples illustrating the effect of pressure will be seen throughout this book (see especially Chapter 20). It should be kept...

Sodium chloride rock salt (NaCl ) has been shown to help improve asparagus production while helping plants to resist disease. 

Protection Offered Sodium chloride rock salt helps asparagus resist crown and root rot diseases caused by Fusarium fungi. 

How to Use Add 2 pounds of sodium chloride rock salt (also sold as pickling salt) per 100. square feet of asparagus bed. Apply the salt in early spring, or later in summer (early July).

Chlorine. Chlorine, the material used to make PVC, is the 20th most common element on earth, found virtually everywhere, in rocks, oceans, plants, animals, and human bodies. It is also essential to human life. Eree chlorine is produced geothermally within the earth, and occasionally finds its way to the earth s surface in its elemental state. More usually, however, it reacts with water vapor to form hydrochloric acid. Hydrochloric acid reacts quickly with other elements and compounds, forming stable compounds (usually chloride) such as sodium chloride (common salt), magnesium chloride, and potassium chloride, all found in large quantities in seawater. 

There are two types of caverns used for storing liquids. Hard rock (mined) caverns are constructed by mining rock formations such as shale, granite, limestone, and many other types of rock. Solution-mined caverns are constructed by dissolution processes, i.e., solution mining or leaching a mineral deposit, most often salt (sodium chloride). The salt deposit may take the form of a massive salt dome or thinner layers of bedded salt that are stratified between layers of rock. Hard rock and solution-mined caverns have been constructed in the United States and many other parts of the world.

As you may know, sodium chloride (table salt) occurs naturally in underground salt deposits. This salt, sometimes called rock salt, has been mined and used for many years as a source of sodium for making other vitally important sodium compounds, such as sodium hydroxide, sodium carbonate, and sodium bicarbonate. In more recent years, the soda ash deposits in Wyoming have become a direct source of sodium carbonate — soda ash is impure sodium carbonate — and, so, mining companies in Wyoming now have a significant share of the sodium carbonate market. 

Perhaps the most important source of sodium chloride is salt mines, large underground reserves of sodium chloride left behind when ancient seas dried up and were buried by the accumulation of rocks and soil. Salt mines are found in many parts of the world, especially Russia, Germany, the United Kingdom, India, France, Mexico, Canada, and the United States. These mines often span many kilometers and... 

Sodium chlorid—Common salt—Sea salt—Table salt—Sodii chloridum (U. S., Br.)—NaCl—58.5—occurs very abundantly in nature, deposited in the solid form as rook salt in solution in all natural waters, especially in sea and mineral spring waters in suspension in the atmosphere and as a constituent of almost all animal and vegetable tissues and fluids. It is formed in an infinite variety of chemical reactions. It is obtained from rock salt, or from the waters of the sea or of saline springs and is the 12... 

Although sodium chloride is by far the most common natural source of sodium, as rock salt or halite, other important sodium salts found widely in nature are sodium borate, sodium carbonate, sodium nitrate, and sodium sulfate. 

Let us again use sodium chloride, common salt, as an example of a substance. We have all seen this substance in what appear to be different forms —table salt, in fine grains salt in the form of crystals a quarter of an inch in diameter, for use with ice for freezing ice cream and natural crystals of rock salt an inch or more across. Despite their obvious difference, all of these samples of salt have the same fundamental properties. 

Sodium chloride NaCl (salt) is the chloride that is produced in the highest quantity. It is extracted from seawater by evaporation, or from salt mines (so-called rock salt). It has many uses in the food and chemical industries.

Sodium is not found ia the free state ia nature because of its high chemical reactivity. It occurs naturally as a component of many complex minerals and of such simple ones as sodium chloride, sodium carbonate, sodium sulfate, sodium borate, and sodium nitrate. Soluble sodium salts are found ia seawater, mineral spriags, and salt lakes. Principal U.S. commercial deposits of sodium salts are the Great Salt Lake Seades Lake and the rock salt beds of the Gulf Coast, Virginia, New York, and Michigan (see Chemicals frombrine). Sodium-23 is the only naturally occurring isotope. The six artificial radioisotopes (qv) are Hsted ia Table 1 (see Sodium compounds).
