Question

The process of sublimation is used on a large scale to obtain common salt from seawater.

• A. True
• B. False

Answer 1

The correct option is B False

Evaporation:

• Evaporation is the process in which water evaporates from the surface of the liquid and is converted into a gaseous state by the action of heat.
• It plays a very important role in the water cycle.
• The liquid constituent of the mixture evaporates leaving behind the solid constituent.
• The evaporation is used on a large scale to obtain common salt from seawater.

Sublimation:

• Sublimation is a process in which a solid substance is directly converted into the gaseous state without going into the liquid state.
• It is used to separate a mixture containing a constituent that sublimes.
• For example, Ammonium chloride, Iodine, etc.

Therefore, the process of sublimation is used on a large scale to obtain common salt from seawater is false.
