The Dead Sea contains approximately what percentage of dissolved solids?

The Dead Sea contains approximately what percentage of dissolved solids?

• A. 3%
• B. 27%
• C. 20%
• D. 15%

Answer: (B)

Dissolved solids refer to the minerals and salts that remain dissolved in water, expressed as a percentage by weight of the water. In very hot, dry environments, evaporation concentrates these salts, making the water extremely saline. The Dead Sea is famous for its high salinity, far above ordinary seawater, which is around 3.5% dissolved solids. Among the options given, the approximate value you’d expect for the Dead Sea’s dissolved solids is about 27%, a figure that reflects its extreme concentration relative to typical seawater. The other numbers are much lower than the Dead Sea’s true salinity, so they don’t fit as well. The dissolved solids are a mix of salts like magnesium, calcium, potassium, and sodium chloride, which together create that highly buoyant, dense water.
