what is the meaning of salt ?
488144
In chemistry, a salt is any ionic compound composed of positively charged cations and negatively charged anions so that the product is neutral and without a net charge. These ions can be inorganic (Cl−) as well as organic (CH3COO−) and monoatomic (F−) as well as polyatomic ions (SO42−).\n\nSalts are formed when acids and bases react.\n\nSolutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity.\n\nZwitterions are salts that contain an anionic center and a cationic center in the same molecule; examples include amino acids, many metabolites, peptides and proteins.\n\nMixtures of many different ions in solution like in the cytoplasm of cells, in blood, urine, plant saps and mineral waters usually do not form defined salts after evaporation of the water. Therefore, their salt content is given for the respective ions.

Salt has been used for thousands and thousands of years--before written language. There wouldn't be any way to tell who first used it. According to the Salt Institute: "Salt was in general use long before history, as we know it, began to be recorded." Check out these websites for more information about the history of salt and food in general.

Not sure exactly what you are asking regarding "substance".  In the diet, salt would have alot to do with low/high pressure and it increases the volume of fluid/blood in your body the heart has to pump.  If you want to lower pressure, decrease your salt intake and processed/fast foods; also no sodas.  Increase water/fluids. Hope this helps.

By "salt," I'm assuming you are talking about rock salt. It lowers the necessary temperature for which the ice cream will freeze, allowing the ice cream to congeal (come together). This provides the texture that we all have come to know and love. People also use rock salt on snow to melt it. The lowering the freezing point of the water combined with the temperature of the snow remaining the same, causes the snow to melt.

The most familiar salt is sodium chloride, the principal component of common table salt.

Salt is a required substance for proper body function.  Granted, too much salt can be bad, but there is a certain amount needed in order for your body systems to work.\n\nSo, like any other necessary substance, when the body detects a shortage of salt, you sense a physiological craving for salt.\n\nOn the other hand, some people (myself included) just have an affinity for salty snacks, so we may occasionally take in too much - has nothing to do with need, just desire.

Salt in the ocean comes from the land. The elements that make up salts, such as chlorine and sodium, started out in rocks. Water and acids eroded the rocks, and rivers carried the elements into the sea. The oceans usually contain 35 parts of salts for every 1000 parts of sea water. This is lower in some places where there is a lot of fresh water coming into the ocean. It is higher where the Sun is very strong and evaporates more of the water. When all the water is gone, the salts are left behind as solid, white crystals.\n\nThe right amount of salt is a very important part of our diet. In ancient times, salt was worth its weight in gold. People used it to flavor and preserve their food. Without salt, the food would spoil. For this reason, salt became a symbol of purity. Some sacrifices in the Old Testament included salt (Leviticus 2:13; Ezekiel 43:24). Jesus called faithful people "the salt of the earth," and the apostle Paul said that our speech should be "seasoned with salt"

NaCl (sodium chloride) is the chemical name for table salt. It has absolutely no caloric value. Therefore 1.5g NaCl = 0 kcal.

Sodium chloride or common salt is the chemical compound NaCl, composed of the elements sodium and chloride. Answer 2 grams of salt/sodium = 2 grams!

Sodium Chloride is an obvious example, as is Potassium Flouride, Lithium Bromide, or any other combination os the alkali metals and halogens from the periodic table.\n\nThe alkali metals are on the far left column of the table, and halogens are on the column 2nd from the right (next to last).\n\nAll of these combinations are collectively refered to as "salts".\nA salt is an ionic compound which contains a metal cation (+) and a nom-metal anion (-).  It is not a requirement that it be a specific type of metal or a specific type of non-metal though, for example, Iron Oxide is also technically a "salt", but it is more commonly refered to as an "Oxide", a more specific type of salt.\n\nhttp://www.webelements.com/index.html

Salt is not salt.\n\nSea salt contains a higher percentage of Potassium Chloride (KCl) than table salt which is mainly sodium Chloride (NaCl). It is the sodium content of salt that can cause damage if too much is ingested. The sodium content of the body's blood, interstitial and intracellular fluids is the key determinant in the volume of water the body retains.\n\nGenerally the more water the higher your blood pressure.\n\nSubstituting the sodium with potassium helps to lower the associated risks of excess salt intake.\n\nHowever excess potassium ingestion hasw problems of its own including dysfuntioning of electrically active cells (heart, nerves, muscles). But the concentrations needed are quite high.

Any acid reacted with any base creates a salt -- that is the definition of a salt.\n\nThe most recognized salt, of course, is table salt -- sodium chloride (NaCl).  This is the product of reacting hydrochloric acid (HCl) with sodium hydroxide (NaOH).  The equation is:\n\nHCl + NaOH ---> NaCl + H2O

The formula for table salt is NaCl (Sodium Chloride). It exists in face-centred crystal lattices.
