Define Crystallization. Write the steps to obtain the pure substance from its aqueous solution.
Answers
What is Crystallization?
Crystallization is a technique used for the purification of substances. A separation technique to separate solids from a solution.
Crystallization Process
The solution is heated in an open container
The solvent molecules start evaporating, leaving behind the solutes
When the solution cools, crystals of solute start accumulating on the surface of the solution
Crystals are collected and dried as per the product requirement
The undissolved solids in the liquid are separated by the process of filtration
The size of crystals formed during this process depends on the cooling rate
Many tiny crystals are formed if the solution is cooled at a fast rate
Large crystals are formed at slow cooling rates
Answer:
crystallization
Explanation:
crystallization is the simple process in which crstaks are used for obtain the pure substance form its aqueous solution.
