This is a Fischer Esterification using the alcohol, methanol,
and the carboxylic acid, butyric acid, to create the ester, methyl
butanoate (smells like apple). After refluxing methanol, butyric
acid, and concentrated sulfuric acid, a separatory flask was used
and the ester was extracted using ice water, then diethyl ether,
then 2 portions of sodium carbonate, and a saturated sodium
chloride brine solution. Anyhydrous sodium sulfate was used after
separation to dry the ester. Please help!!

Procedure Esterification Each group will be assigned an unknown alcohol by the instructor. Record the unknown number and then add the contents of the vial (25 mmol of alcohol) to a 50 mL round bottom flask with a stir bar Then add 2.75 mL (approx. 50 mmol) of acetic acid followed by 0.25 mL of concentrated sulfuric acid Add a reflux condenser then reflux the mixture in a sand bath with stirring for one hour....

Thumbs up for good answer. Why does the liquid in the round
bottom flask turn light pink?, please explain (This happened
during/after step 2). This is the procedure and the experiment is
called Synthesis of Artificial Flavorings by Fischer
Esterification.
Thank you!
