What is Acid-Base Extraction of Benzoic Acid about?
The document describes a chemistry laboratory experiment on acid-base extraction. The objectives were to extract benzoic acid and p-dichlorobenzene from a mixture using acid-alkaline extraction. Sodium hydroxide solution was used to extract benzoic acid into the aqueous layer, while p-dichlorobenzene remained in the ether layer. Percentage recoveries of 71.1% for benzoic acid and 45.2% for p-dichlorobenzene were obtained. Melting points were also measured and were close to the theoretical values.
