Question

Crystallization of sodium chloride from its aqueous solution is ___ change.

Answer 1

Crystallization of sodium chloride from its aqueous solution is physical change.

Solution:

• In crystallization from an aqueous solution, there is no chemical change that takes place.
• Only change that happens is that the sodium chloride gets rid of water molecules and crystals of sodium chloride are formed.
• This is only a physical change where water is evaporated to get molecules of sodium chloride in crystal form.
