Prepare Benzoic Acid From Benzaldehyde Experiment - Summary
In this experiment, we will learn how to prepare benzoic acid from benzaldehyde. Benzoic acid is widely utilized as a standard substance in calorimetry and acidimetry, with “standard samples” provided by the National Bureau of Standards for many years. Research by Morey! evaluated the effectiveness of benzoic acid as a primary standard in acidimetry and alkalimetry.
Importance of Accurate Measurements
As the methods for making comparative measurements advance, there is a growing demand for accuracy in determining the properties of standard substances. Achieving a high level of accuracy in the initial assessment of this reference substance requires not only a considerable uniformity in composition but also an almost perfect purity.
To Prepare Benzoic Acid from Benzaldehyde Practical
Aldehydes, when oxidized, produce acids. Benzaldehyde, when heated with an alkaline potassium permanganate solution, yields benzoic acid. This process illustrates an oxidation reaction.
Many properties of various substances are assessed through comparative methods rather than absolute methods. The precision of these comparative methods relies on the accuracy of the measurements, along with the known properties of the standard substance used for comparison.
