An organic compound was extracted into dichloromethane and then the aqueous layer is shaken with saturated sodium chloride solution. What is the purpose of the sodium chloride?

The sodium chloride serves to pull out the water from the organic layer to the aqueous or water layer

Explanation:

Shaking it with sodium chloride also called brine pulls the water away from the organic composition to the water layer due to the affinity of the salt to absorb more water and become less concentrated and dense as the salt has more ability to absorb the water than to absorb organic compounds
