The fatty acids are soluble in the alkaline solution used for hydrolysis and that's why, salt is added so that sodium salt of fatty acid is formed and it gets precipitated out. Therefore, sodium chloride is used in the soap industry for soap's precipitation

Sodium chloride, also known as table salt, plays a crucial role in the preparation of soap. When fatty acids or oils are treated with sodium hydroxide (NaOH), they undergo a process called saponification, which results in the formation of soap molecules and glycerol. Sodium chloride is added to this mixture to help the soap molecules separate from the glycerol more easily. This is because sodium chloride helps to increase the solubility of the soap molecules in water, allowing them to form a separate layer on top of the glycerol.
Moreso So, Adding NaCl to this mixture helps to induce the precipitation of the soap, allowing it to be separated from the glycerol. This process is known as "salting out" and is used to purify the soap and remove impurities.
the correct option would be "separate the soap from glycerol
