Map of the concentration of salt
in the ocean in g / 1000 g sea water
DATA and INFORMATION
Ion concentration in the water
ion concentration mg / L sea water
Cl- 224000
Mg2+ 44000
Na+ 40100
Ca2+ 17200
K+ 7650
Br- 5300

Other information
  • Lowest place on earth: - 480 m vs. ocean level.
  • Evaporation of the lake's waters: 1,4 m a year (estimated)
  • The salt concentration is 10 time higher than the one of the ocean
  • The density of the water is 1.24 g/mL
  • Water temperature at the lowest level of the Dead Sea: 22 °C (constant)
Assumption No ion pairing (which is probably wrong a those concentrations!)
