Solution

Salt in seawater

  • Numerous dissolved salts are present in the seawater.
  • Specialized methods are used to separate the salt from the ocean.
  • Since salt and water form a true solution, it is impossible to separate by simple physical techniques.

Evaporation Method:

  • The evaporation method is used to separate salt from seawater.
  • As water molecules absorb heat from the Sun, they transform into water vapors that disperse into the atmosphere, leaving behind salt since salt has a much higher boiling point.

So, an evaporation method is used to separate salt from seawater.
