where is sodium commonly found?

Sodium does not exist simply as a metal in nature - it's too reactive, so it is found as a compound. Sodium is the sixth most abundant element in the earth's crust at about 2.6 - 3.0%. The most common mineral is rock salt (sodium chloride, NaCl, or halite), but it occurs in many other minerals including sodium borate (borax), sodium carbonate (soda), sodium nitrate (Chile saltpetre). and sodium sulphate (thenardite).

it does but it's diluted.Some bodies of water have higher salt content than others.

Solid. The only liquid ones are bromine and mercury I think.\nPotassium is a soft silvery-white metallic alkali metal that occurs naturally bound to other elements in seawater and many minerals

yes, it's high in sodium but you can buy a low sodium variety.

Salt or Sodium Chloride is highly soluble in water.  Salt is naturally occurring and large bodies of water that cover vast numbers of square kilometers come in contact with salt.  Over time it dissolves causing the water to be high in TDS or total dissolved solids such as NA CL.  When the water from oceans evaporates, the salt drops out of solution which increase the salinity of the remaining water.   The evaporated water returns to earth as fresh water which flows back into the oceans and the cycle continues.   Large Salt caverns are ancient spaces that have not been exposed to water for millions of years.

Did you ever wonder why the oceans are filled with salt water instead of fresh? Just where did the salt come from? And is it the same salt you find on a dining room table? Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents. When water evaporates from the surface of the ocean, the salt is left behind. After millions of years, the oceans have developed a noticeably salty taste.\n\nDifferent bodies of water have different amounts of salt mixed in, or different salinities. Salinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt.\n\nThe average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.\n\nFreshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries (where fresh river water meets salty ocean water) are examples of brackish waters.\n\nMost marine creatures keep the salinity inside their bodies at about the same concentration as the water outside their bodies because water likes a balance. If an animal that usually lives in salt water were placed in fresh water, the fresh water would flow into the animal through its skin. If a fresh water animal found itself in the salty ocean, the water inside of it would rush out. The process by which water flows through a semi-permeable membrane (a material that lets only some things pass through it) such as the animal's skin from an area of high concentration (lots of water, little salt) to an area of low concentration (little water, lots of salt) is called osmosis.\n\nThis is also why humans (and nearly all mammals) cannot drink salt water. When you take in those extra salts, your body will need to expel them as quickly as possible. Your kidneys will try to flush the salts out of your body in urine, and in the process pump out more water than you are taking in. Soon you'll be dehydrated and your cells and organs will not be able to function properly.

Salt comes from  dissolved rock. Rivers carry that salt from the land to the ocean. It's that simple.

Well sodium isn't nesecessarily bad but only in moderation. If you are frequently eating stuff with over 10% of your DV then that is too much. Excess sodium will lead to water storage which in turn is water weight. If you are trying to lose weight I'd opt to stay away from sodium if possible.

It's usually only prescribed for people on diuretics for blood pressure. Potassium is so widespread in food that it is not needed as a mineral supplement. BTW, good natural sources of potassium are potatoes, bananas and orange or tomato juice.

2 grams is the amount they use in a low sodium diet. That's about as low as you should go.

Oceans and seas are salt water,but the most salt water on earth could be found in the dead sea in Jordan in the Middle East.

Normal blood sodium level is 135 - 145 milliEquivalents/liter (mEq/L), or in international units, 135 - 145 millimoles/liter (mmol/L).

Salt when dissoved in water dissociates an forms Sodium+ and Chlorine- ions.Sodium in free state immediately reacts with oxygen and burns.That's the reason why sodium is stored under kerosene.When the water containing salt comes in contact with a wound,the Sodium gets deposited on our wounds and starts oxidising and burns our skin which hurts us.

The concentration of salt in seawater varies with temperature.  Because the Arctic and Antarctic oceans are colder than the Indian Ocean and South China Sea, the salt is less soluble.  By the same principle, seawater near the floor of the ocean would be less salty because it's cold down there.  Throw in a few baby volcanoes, the Atlantic rift and a few dozen fumaroles, etc...  Then, you would have to know how many liters of water are in the oceans and that quantity is constantly changing.  Now, are you talking about common NaCL?  Or do you want to include all the sulfates, carbonates, phosphates, etc... which are all in the ocean?  Thanks for the easy 2 points!

Where do you find water that often?
