Final answer:
The balanced equation for the acid-base reaction in extracting carboxylic acid and recovering it from the aqueous layer.
Step-by-step explanation:
The balanced equation for the acid-base reaction that occurs when the carboxylic acid component is extracted from the ether solution is:
CH3COOH (acetic acid) + NaOH (sodium hydroxide) → CH3COONa (sodium acetate) + H2O (water)
The balanced equation for the acid-base reaction required to recover the carboxylic acid from the aqueous layer is:
CH3COONa (sodium acetate) + HCl (hydrochloric acid) → CH3COOH (acetic acid) + NaCl (sodium chloride)
