How do i separate free fatty acids from an ester?

Accepted Answer

You can separate free fatty acids from an ester using hydrolysis or saponification.
Hydrolysis involves breaking the ester bond using water in the presence of an acid or base catalyst. This produces the free fatty acid and an alcohol.
Saponification is a specific type of hydrolysis that uses a strong base, such as sodium hydroxide (NaOH), to break down the ester. This process is used to make soap, where the free fatty acid forms a salt with the base.
