Crystallization is the correct answer for recovering salt from a solution by evaporating the solvent
Answer:
a is write
Explanation:
Why are all ionic compounds crystalline in structure?
Ionic compounds are generally hard, but brittle. ... The repulsive forces between like-charged ions cause the crystal to shatter. When an ionic crystal breaks, it tends to do so along smooth planes because of the regular arrangement of the ions.
An exchange reaction consists of both synthesis and decomposition reactions.
Here’s a complex example: AB + CD → AC + BD.
Another example might be: AB + CD → AD + BC.
