Can anyone explain what the uses of Saltpeter are and how it is used?

Saltpeter, or potassium nitrate, along with sulphur and charcoal, is used to make black powder, the first practical explosive.  It lead to the creation of firearms, which radically changed how wars were fought.

---Deliquescent salts have a great affinity for surrounding moisture, and readily absorb water vapours to form a solution. E.g: calcium chloride; zinc chloride, magnesium chloride; sodium hydroxide(base); lithium chloride; ammonium nitrate; magnesium nitrate; lithium sulfide; magnesium iodide; and potassium chloride\n\n---Hydrated salts are those which contain water of crystallization - different  salts attract different number of water molecules. E.g: Na2CO3+10H2O ; MgSO4+7H2O;  CuSO4+5H20;  CoCl2+6H2O;  SnCl2+2H20;  nickel(II) sulphate;  aluminum nitrate ; lithium nitrate;  calcium nitrate;  CaCl2+6H2O;  and BaCl2+2H2O.\n\nCrystallization is the the process of the removal of a solid from a solution by increasing its concentration above the saturation point, such that excess solid separates out in the form of crystals. It is used in separation and purification of a substance.

salt is a flavor enhancer. whatever you put it on it brings out the flavor. salt by itself tastes terrible

Since you didn't say what results you desire it is not really possible for anyone to answer your question.\n\nBut KNO3, potassium nitrate, commonly called "salt peter", is an oxidizing agent used in gun powder.  It can also be used as a fertilizer.  It is also a diuretic, although a poor one and humans should not use it.

I know of two ways.\n1. It is mined from deposites underground.  They used to do this near where I grew up as the chlorine in the salt was used in the processes at the nearby chemical plants.\n\n2.  It is evaporated from ocean water.  Once the water is evaporated mostly what's left is just regular salt.  It just has to be cleaned up a bit.

Common Salt (Sodium Chloride) is what's known as a drying agent. This means that it will absorb water and many other liquids. Because smails ( and slugs) are composed mainly of water, a small amount of salt can completely dry them out.\n\nHowever, humans are mainly composed of water as well, so how come we don't dry ou with salt as well? The difference is that snails are covered a selectively permeable membrane, which lets through small molecules (like water), whereas we have a very thick skin which doesn't let through nearly the same amount of water as it does with snails and slugs.

I agree that buried PVC should be okay for this use, but as fuel prices rise the transportation costs of trucking the salt back the ocean and the permitting involved in dumping truckloads of salt into the ocean will become a problem.  You could re-slurry the salt and use gravity to pipe the salt-slurry back to the ocean, but the intake line and exit line would need to be very far apart and the currents would have to be analyzed so that the salt isn't sucked back into the line.\n\nAlso, your pumping piping and pumps will need to be evaluated to prevent corrosion.

It is used to - \nsupply zinc in animal feeds, fertilizers, and agricultural sprays. \n\nZnSO4·7H2O is used in making lithopone, \nin coagulation baths for rayon, \nin electrolytes for zinc plating, \nas a mordant in dyeing, \nas a preservative for skins and leather \nand in medicine as an astringent and emetic.\n\nZinc sulphate can be used in the eye as an astringent to relieve over production of tears. \n\nThey can be particularly useful in those suffering from eye infections, in which watery eyes can be a problem.

There are all sorts of salts:\nacid + base = salt + water\nHCl + NaOH = NaCl + H2O\n\nNaCl is sodium chloride. This is the same stuff we use at the table. If you have a look at the packet it came in you will probably find there are a few other things in the 'table salt' too - perhaps some iodides and an anti-caking agent to keep it running freely.\n\nMore info. on 'table salts':

Medicated salt blocks are used to administer anti-parasitic, ephedrine and other drugs to livestock.\n\nLivestock need salt to metabolize protein.\n\nThere is a large illegal trade in veterinary ephedrine medicated salt blocks. The ephedrine is extracted and used as an illegal stimulant or weight control drug. But more importantly, ephedrine is used in illegal labs to create the potently addictive and dangerous methamphetamine drugs sold illegaly.

The chemical compound potassium nitrate is a naturally occurring mineral source of nitrogen. It is a nitrate with chemical formula KNO3.\n\nIts common names include saltpetre (from Medieval Latin sal petrae: "stone salt" or possibly "Salt of Petra"), American English salt peter, Nitrate of potash and nitre. The name salt peter is also applied to sodium nitrate.\n\nA popular misconception is that potassium nitrate is an anaphrodisiac and was added to food in all-male institutions. In fact, potassium nitrate has no such effect in humans. [2]

I am not sure what will there be full form for "salt" in this context, but salt is just generic term in password protection in UNIX environments, where addition of slat bits makes stronger hash code,little difficult for bruteforce programs or other kind of password crackers to break passwords with addition of "salt".\n\nLet me know if this useful.

Salt water works better because it's a better conductor of electricity as opposed to just tap water.  In salt water, you have a solution of both Cl- and Na+ floating about creating a means of transferring electricity (electolytes).  So, instead of a saltbridge to provide the transfer of ions, all the ions needed are right there, which will quickly drain the battery.  Think of it as a short circuit - you have a large current because the path of resistance from the cathode to the anode is nothing.  Plus, there's plenty of ions to provide that means of conduction.

A salt is an ionic compound that is composed of a metal and non-metal. \nThere are many different kinds of salts. Table salt, the kind you put on food is Sodium Chloride (NaCl) and it can be found in concentrations in the Earth known as "salt domes" or derived from sea salt or halite formations.\n\nSea salt, another kind of salt commonly used in cooking, has varying compositions depending on where it is harvested but generally contains more chloride than sodium and has trace amounts of sulfites, calcium, and other metals. These metals are not in pure form, but combined chemically with non-metals.\n\nSalts can be the byproduct of a chemical reaction as is often the case when an acid and base are mixed. The base and acid neutralize to form, among other things, a salt in an aqueous solution. Many salts are poisonous to humans. \n\nFor more information go here: http://en.wikipedia.org/wiki/Salt

Sodium acetate is used in the textile industry to neutralize sulfuric acid waste streams, and as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning, and it helps to retard vulcanization of chloroprene in synthetic rubber production. Sodium acetate may be added to foods as a preservative; in this application it is usually labelled E262.\n\nAs the conjugate base of a weak acid, a solution of sodium acetate can act as a buffer to keep a relatively constant pH. This is useful especially in biochemical applications where reactions are pH dependent.\n\nSodium acetate is also used in consumer heating pads or hand warmers. When sodium acetate trihydrate crystals are heated to 100 °C, water is driven off to give a supersaturated solution of sodium acetate in water. By clicking on a disc in the heating pad, a nucleation center is formed which causes the solution to crystallize into solid sodium acetate trihydrate again. The bond-forming process of crystallization is exothermic, hence heat is evolved.

Need to be more specific in your question.  There are many different types of salts, each with their own densities.

It's because salt is an electrolyte, a substance containing ions (charged atoms or molecules). The charges are what allow the atoms to conduct electricity, I think.
