Dead Sea is a salt lake or inland sea located in the Jordan Valley. The surface of the Dead Sea is over 1,300 feet below the sea level. It has got the most saline water on Earth with salinity ranging from 28% to 35%. Normal sea water shows the salinity of 3 to 6%. Hence the Dead Sea is almost 6 times saltier than the normal sea water. The Dead Sea gets saltier as we go deep inside it. Below 300 feet inside the Dead Sea, the dissolved salt concentration approximates to 332 grams per kilogram of seawater and it is said to be the saturated amount of salt in water.

When substances dissolve in a liquid, the density of the liquid increases. The dissolving molecules mix with the liquid molecules, so each drop of liquid now has more molecules in it. Sea water has salt and other substances dissolved in it that makes it more dense than fresh water. Dead Sea water has a clear, blue–green color and a bitter, nauseous taste and is slightly oily to the touch.
