Many operations in the chemical laboratory use “salting out” in the procedure. What do the purpose of this technique?
What is the purpose of including a melting point in a procedure? A) As a method of purification - We can purify a substance. B) As a method of encouraging synthesis - Reagents are always more reactive in the liquid state. C) As a method of encouraging a substance to dissolve - Free molecules in the liquid state can make interactions and dissolve in the solvent easier. D) As a method of characterization We can identify an unknown substance. -- O A OD
