    For the most part, the various grades of salt are all the same; chemically most are greater than 99% sodium chloride, but the structure varies widely. Simple table salt consists of small, compact cubic grains, while kosher salt has a much more irregular structure and a larger surface area. Popcorn salt is ground salt that dissolves very quickly. Rock salt is just that, large chunks of sodium chloride. These differences in structure can cause a significant change in the perceived flavor of the salt and its usefulness for particular recipes. The speed with which it dissolves is also very important, with finer salts such as pickling salt even dissolving readily in cold liquid.

    Table salt also contains anti-caking agents to allow it to flow freely, and sometimes contains very small amounts of iodine.

    Sea salt, which is made from evaporating seawater, also varies considerably. Because there are impurities in the water, each sea salt has a unique taste and is prized in different cuisines or for different applications. Sea salts often tend to cost considerably more than other kinds of salt; however, in areas with large seawater evaporation industries (such as California) the "table salt" in local stores may actually be sea salt.

    Rock salt is nearly pure sodium chloride.

    Sea salt, while mostly sodium chloride, is a mixture of many salts. Of course, rock salt is in crystalline form while sea salt is an aqueous solution.

    I piss on table salt. Shake it when dry thus making rock salt.

    I stopped eating poo as the lack of chocolatey taste diminished

    Rock salt-This is the common name for the mineral "halite". Its chemical formula is NaCl. Most of us know this substance as table salt. and... Actually, rock salt is not K2SO4; it is NaCl. It can have impurities of gypsum (CaSO4) and sylvite (KCl) but it is very rare to find potassium sulfate as a mineral, although occasionally polyhalite (K2Ca2Mg(SO4)4.2H2O) is found associated with rock salt deposits. It is typically formed by the evaporation of salty water (such as sea water) which contains dissolved Na+ and Cl- ions. Table salt is essential for human life. A large amount of the comercially mined rock salt is prepared for human consumption. Rock salt is also applied to road beds in cold climates to help reduce the freezing point of water on the road, thereby allowing it to not freeze-over at 0 deg. C

    Sea salt-, obtained by evaporating seawater, is used in cooking and cosmetics. Historically called bay salt, its mineral content gives it a different taste[citation needed] from table salt, which is pure sodium chloride, usually refined from mined rock salt (halite) or from sea salt.

    Sea salt and table salt have the same nutritional value. The real differences between sea salt and table salt are in their taste and texture.

    Sea salt is harvested from seawater through evaporation. Table salt is typically from rock salt, which is mined from mineral deposits. Both types of salt can be fully refined, and the end result is pure sodium chloride. Variations in the refining process result in different forms of salt.

    Table salt is a fine-grained salt that often contains added iodine (iodized salt). Iodine is necessary for normal thyroid function. Some table salt may also contain anti-caking ingredient.

    Sea salt is available in fine or coarse grain. Sea salt has a slightly different taste than table salt because of different minerals it contains. Many people prefer sea salt to table salt because they claim it has a more subtle flavor. Sea sat doesn't contain iodine or any other additives. However, if you use sea salt you typically don't have to worry about not getting enough iodine in your diet because iodine is available in many other foods, including dairy products, seafood and many processed foods.
