3.The Dead Sea is famous throughout the world for being the owner of a unique and surprising talent: its high amount of salt favors the flotation of large objects.
It is located between the borders of Jordan, Israel and the West Bank. In addition, it is considered the lowest point on the planet, 400 meters below sea level. The Dead Sea is divided into two large basins separated by a land bridge. The first of them measures almost 50 kilometers in length, while the second barely reaches twelve. Together, they exceed 400 meters deep.
As we mentioned above, this sea has a good dose of salt among its components, about 340 grams per liter. Why does this happen? Experts say it is due to the strange combination of two factors: the amount of fresh water it receives from the tributaries is not enough to cope with the evaporation of salt water. This is composed of several mineral salts that also enhance the flotation: sodium chloride, potassium chloride, magnesium chloride and calcium chloride, among others.

5.Hydrated salt- A hydrated salt is a crystalline salt molecule that is loosely attached to a certain number of water molecules. Salt is created when an acid's anion and a base's cation are combined to produce an acid-base molecule. ... In a hydrated salt, the water molecules are incorporated into the crystalline structure of the salt.
Anhydrated salt- The word “anhydrous” means without water. An anhydrous salt is only the cation and anion making up the salt. There is no water of hydration. Many salts naturally draw water from the environment and occur in nature as hydrated salt.For every every formula unit of copper II sulfate there are five water molecules.
