does anyone know how i could make synthetic sea water with just regular salt?

, you can´t make seawater with regular salt because of the contents but if you want to make a equivilant it would be 2/4 cups of salt and 2 cups of water\n \nHere are some other facts for your sister to use in her writen report of the project.\nSeawater has one of the most stable constitutions, varying only in a few places in its 77% coverage of the earth's surface. This factor makes keeping marines more difficult than freshwater species as the fish involved have little tolerance to changing conditions - they never encounter any - but, advantageously it means that all marine fish will be at home in one common type of water. \n\nExcept for those few aquarists who have access to natural tropical seawater, the majority of marine fishkeepers have to rely on preparing their own synthetic variety using commercially-available salt mixes.\n\n \nTo make sure the water is mixed to the correct conditions, test the 'strength' of the mix by measuring the Specific Gravity (S.G) of a sample. \nIn Nature, this approximates to 35 ppt (parts per thousand) or, in practical terms 35 grams of salt per litre of water, approximately S.G of 1.025; in this example, the S.G of the sample reads 1.024 which is satisfactory for a reef tank but could be lower (1.021-1.023) for a 'fish only' collection.\nIt is important to measure the S.G. when the water is at the correct temperature (75oF) and thankfully most hydrometers offered at the aquatic outlets are calibrated at this value. \n\n\n\n\nSynthetic seawater should be mixed in clean plastic containers and aerated for at least 24 hours before use.\n\nOne of the curses of the marine aquarium (not helped either by the intense lighting found on most systems) is unwanted algae; this is further encouraged by phosphates and nitrates found in the water used to make the seawater. \nAlways use a salt-mix that is labelled 'phosphate and nitrate free' and also make sure that water used is also free of these substances too.\n\nSource water can range from absolutely free of anything tapwater (via Reverse Osmosis treatment), nitrate removed by a Nitragon unit or phosphate removed by using RowaPhos(tm) in a filter.\nAdditionally, clean rainwater can be used.\n\nNitrate levels can be kept to a minimum im the aquarium by the action of use anaerobic de-nitrifying bacterial colonies within Living Rock, and by regular partial water changes. The build up of nitrate can also be minimised by using a protein skimmer to remove organic substances from the water before the nitrite-forming and nitrate-converting bacteria can get their hands on them. \n\nKeep a check on pH and nitrate levels: rising nitrate levels and a falling pH means it's time for a water change. Whilst nitrate levels in a fish-only collection can be allowed to rise, invertebrates appreciate really low levels (zero, preferably

There is no "artificial" salt, only refined (cleaned) salt.\n\nSea salt contains other ions - mainly potassium, calcium, magnesium, sulphate and carbonate. It may also contain some remnant water (at least there is a special salt the French produce in the Mediterranean which does).\n\nMineral salt from mines is comparably pure.\n\nSome varieties of table salt get iodide additions to make up for natural deficits of iodine in inland regions.

Sea water being salty, is not drinkabl. With the peoper apparatus, you can ue the sun to evaporate the sea water. Then you have to catch it as it condenses. The salt does not evaporate.Now it is drinkable.  Mineral water essentially is water from the ground that has minerals from the earth dissolved in it. When this is evaporated the minerals do not evaporate either. You can get drinkable water from sea water, but not mineral water.

There is a product made by HTH called pH Minus. (I'm sure there are other company's that make it as well), it's fairly inexpensive, around $14.00 for 1/2 gal. Just follow the directions and your water will be back to normal in no time at all. It works quickly! GOOD LUCK!

boil water and add teaspoon of salt, pour into container and refrigerate for a day\npour out and wash container\nsmell should be done

I really dont know why you would do this.. If you want to do it.. go get sand from the beach.. dump it in the bottom of your pool.. and stir.. sand will go to the bottom, the salt will saturate your water.. \n\nAgain.. why you would want this. i dont know

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

I'm not entirely sure that that would actually explode.\n\nYou mixed salt water, salt substitute-water, alcohol, carbon and then the potassium p and ammon chlor.\n\nThe chloride and potassium may undergo a replacement reaction, but I doubt it would explode unless you actually lit it with a flame. You made great sidewalk salt though, go melt some ice :)

Sure, take a plastic bottle, like an empty coke bottle.  Punch a couple of holes in it, and put in a little piece of cork or styrofoam.  Fill it with real salty water (you'll need a lot of salt!).  Since salt water is heavier than pure water, it will sink, but after awhile the salt water will run out of the holes and fresh water will replace it, and the cork or styrofoam will make it float.  You'll have to experiment with the size of the piece of styrofoam, it needs to be small so it barely makes the bottle float.\n\nGood luck!\n\nAnd make sure your floating piece isn't going to soak up water, or of course it won't work.

Believe it or not, Chlorine is not found naturally.  There are many compounds that can be used as precursors to make Chlorine.  Mostly, Sodium Chloride is put through an electrolysis reaction in water to yield chlorine.  Another  way to make Chlorine is to react Manganese Oxide (The same compound found in regular AA, AAA and C batteries) with Concentrated Hydrochloric Acid.  \nPlease see my sources for more information.

in the middle of the sea on  a small boat.... I dont know.  On a ship or at a lot of resorts there is one common way... Reverse Osmosis.  Plain and simple, it's pushing the water through a series of filtrations... multimedia and then through membranes at high pressures.  It is then treated with a variety of chemicals.\n\nThe old way to do it on ships is through multi-staged flash-type distilling plants where the water is boiled at 68F-72F under a vacuum and then treated with a Brominator.

Distill the water. The WATER comes out of the tubes, not the salt.\n    As for testing, just drink a little of it. Do you *LIKE* it?\nNo? Well you better make sure that you don't put it back in the same cup you used for collection.\nOK the water will still pass an electric current through it if it has any impurities. Completely pure water will not.\nUnless you use more than around one volt, in which case the bubbles you see escaping will be hydrogen and oxygen. That means you've gone too far with the testing part.

The ocean is essential for life on Earth, and also helps make the climate fairly moderate. However, although the ocean contains 1,370 million cubic kilometres (334 million cubic miles) of water, humans can’t survive by drinking from it—it is too salty.\n\nTo a chemist, ‘salt’ refers to a wide range of chemicals where a metal is combined with a non-metal. Ordinary common salt is a compound formed when the metal sodium combines with the non-metal chlorine—sodium chloride. This contains electrically charged atoms, called ions, that attract each other, resulting in a fairly hard crystal. When salt dissolves, these ions separate. Sodium and chloride ions are the main ions in seawater, but not the only ones. The salty seas benefit man, because the ocean provides many useful minerals for our industries.

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.

In synthetic organic chemistry, water free ethanol can  be produced by adding elementary sodium wire under a nitrogen atmosphere. The sodium will react with water forming NaOH and with the ethanol forming sodium ethanolate, which in turn would react with any water that should make its way into the liquid.\n\nTo remove the salts, you can distill in a water free environment.\n\nSodium wire is highly inflammable. You won't be able to get it outside of laboratories, for a good reason.
