can salt disolve in water? If so, How?

Yes, of course "salt" (table salt) can dissolve in water.\n\nThereare, however, many types of salts.  "Salt" is a general term refering to an ionic compound formed with a metal cation (+) and a non-metal anion (-), but it has come to commonly refer to table salt [NaCl] by most common people.\nSince salts are ionic compounds, they are soluble in water.  Some salts are very soluble, others only slightly, others are almost totally insoluuble.\nSodium Chloride (NaCl) is very soluble, but other salts like Silver Chloride (AgCl) are almost totally insoluble.\n\nHave you ever heard of the "like dissolves like" rule?  It states that polar solvents (like water) can dissolve ionic or polar solutes (like salt).  Non-polar solvents will dissolve non-polar solutes.\nThe polar water molecules will surround the Ions making up the salt, breaking it up into ions and placing it in solution.\n\nWhen you dissolve table salt in water, it forms an aqueous solution of Na+ and Cl- ions.\nSince the Na+ ion has a positive charge, it is surrounded by the Oxygen end of a water molecule which has a slight negaitve charge due to the two lone pairs of electrons surrounding it and the difference in electronegativity between the Oxygen and the Hydrogen atoms.  Since the Chloride ion has a negative charge, it is surrounded by the Hydrogen side of the water molecule.\n\n\n"corrupted_bunny" doesnt know what she is talking about.  Table salt very much so dissolves in water.  Melting is a completely different process than dissolving.

methane wouldnt really dissolve in water.  KCl would ionize in water to become K+ and Cl-.  Helium wouldn't dissolve in water.  MgSO4 would also ionize in water.  Sucrose would dissolve in water to a significant extent, because of hydrogen bonding.  Sucrose has lost of hydroxyl groups in its structure and allow it to hydrogen bond in water, therefore dissolving.  Sodium bicarb would also just ionize.

yes... it's called reverse osmosis.\n\nBasically it pushes the sea water through a filter that doesn't allow the salt to pass.\n\nAlso there is turning the water into steam and then condensing it into liquid again.  This leaves the salt behind as it is converted to steam.\n\nDesalinization is usually expensive and not very efficient either.

Distill it.\n\nIn cooking, supposedly you can put a piece of raw potato (sometimes, the hint says a piece of lettuce) in food that's too salty and it takes the salt out.  But I don't know if that works.  I'd go with distillation.  \n\nDistillation is where you boil a liquid and then catch the vapor and condense it.  In the case of salt water, the vapor would be plain water with nothing dissolved in it (the salt gets left behind in whatever you use to boil the liquid in.)  Distillation is also used to make an alcoholic liquid more alcoholic.  I guess the alcohol gets vaporized and condensed.

Do not crush the rock salt as this will make the impurities harder to remove.\n\nDissolve the rock salt in very hot water and filter.  If the filtrate (the water that comes through the filter) is colored, then you might need to treat it with charcoal to remove these soluble impurities.\n\nOnce you have a clear solution, allow some of the water to evaporate until the solution becomes saturated.  A single seed crystal will start the formation of sodium chloride crystals from the solution.  Stirring will keep the crystals smaller, otherwise you can end up with one very large crystal of salt.\n\nThis crystallization process is what does the final purification.  The crystals formed will be almost pure sodium chloride.

Everyone who has been to the beach knows that seawater is salty. Everyone also knows that fresh water in rain, rivers, and even ice is not salty. Why are some of Earth’s waters salty and others not? There are two clues that give us the answer. First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.\n\nAs rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.\n\nA second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other. \n\nThe Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level. \n\nRivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.\n\nA final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.\n\nWill the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal processes ar

i'd say you have a basic understanding of molecular chemistry, micki.\n\nhowever, to improve your hypothesis, have it say:  I think the lower temperature the slower the salt will dissolve.  This is because the ions in a salt crystal require energy to dissolve away from the rigid crystal form the are in.  there is less energy present in cold water, therefore, the cold water will take longer to dissolve the salt crystals.

Take 33g of the salt and dissolve it in 67 g of water to get 33% salt solution.\n\nIts not the same as 0.3 N solution

I think if you put salt in water and electrisize it you can see salt react but dont trust me.

Na+ and OH- you are dissolving a salt\n\nby the way, i am getting a phd in chem, so trust me. also, there are tons of answers in there that are totally bullshit.

Sea salt melts it quickly.\n\n\nPeace

The Ksp for a salt is a constant and should not change in response to solution volume.  However, we must be careful not to forget the definition of Ksp.  The Ksp of an alkaline earth hydroxide that dissociates according to the following reaction is:\n\nX(OH)2 <----> X(+2)  + 2OH(-1)\n\nKsp = [X][OH]^2\n\nIn other words we simply multiply the concentration of the metal ion by the concentration of the hydroxide ion squared, but ONLY IF THE DISSOCIATED IONS ARE IN EQUILIBRIUM WITH SOME UNDISSOCIATED SOLID!!  So there must be some undissolved solid that remains.  If we add so much solvent that the solubility limit of our salt is not reached, and it dissolves entirely, then we can NOT make any measurement of the Ksp.\n\nIn short the answer is:  This will have no affect on the calculated Ksp as long as the additional volume of solvent added did not cause all of the salt to dissolve.

The salt gets dissolved in the water.

A grain of salt.  It won't dissociate under physical pressures except for extreme temperature (800 Celsius) but will dissociate into sodium and chlorine ions in the presence of water.

Sounds like a trick question. In the north we know that putting salt on ice makes it melt. In the arctic regions only the salty sea water is still water. The ice and snow are actually fresh water. Salt lowers the temperature that water freezes at. However, if you can freeze dry the salt it will separate from the water. This is the method that's used to filter Ice Beer. So technically you could if done right but just freezing it is a difficult process because you'll need something very very cold as a coolant. This would be a good series of experiments if you can get someone that can handle dry ice (frozen C02).

Simple, just follow this process respectively. Since its one whole of a solution. Begin with distillation. This will get rid of the oil, sand+dirt and the salty water. \n\nDirt+sand - you could add water and then sieve the dirt and water. as for the dirt distilation.\n\nSalty water - you just need to heat the solution and distill the vapour to have your water other wise the salt will form crystals and loose water to the atmosphere thus nice dry sodium cloride crystals. \n\nHope you got answered....

Salt occurs as (Na+Cl-) \nThe water molecules come between the atoms of salt , and thus breaks the ionic bonding b/w Na+ and Cl-.Na+ is attracted to the lone pair of oxygen atom of the water molecule and Cl-to the H atom of water molecule , thus hydrolysis and solvation of salt occurs, which makes the salt to dissolve fast whereas in sugars, the molecules are quite big and moreover sugar has a planar geometry , and contains bonds like -C-H, -C-OH-, -C-O-C-, these breaking of these bonds require more energy and moreover -C- is non-polar, thus increasing the no. of C atoms will make a compound to dissolve less in water. Sugar has 6 Carbon atoms.\nThus to dissolve sugar , we need stirring.
