Question
Chapter 20.5, Problem 20.6P
(a)
Interpretation Introduction
Interpretation:
The use of acid-base extraction to purify pentanal is to be shown.
Concept introduction:
Acid-base extraction is the technique used to separate the acidic and basic substance from the mixture on the basis of their chemical properties. This technique used during the work up of a reaction after the synthesis of the compounds, so that product becomes free from any type of impurities. The acidic or basic substances that are similar in chemical properties are impossible to separate through this method.
(b)
Interpretation Introduction
Interpretation:
The expected impurities that cannot be removed from pentanal by acid-base extraction and how that impurity can be removed are to be stated.
