![]() “How to Make a Benzoic Acid Snow Globe.” ThoughtCo, Jul. “Sodium Benzoate.” Wikipedia, Wikimedia Foundation, 3 Nov. Both these are organic compounds because both these compounds have the aromatic benzene ring, substituted with a carbonyl group. The key difference between benzoic acid and sodium benzoate is that benzoic acid is the simplest aromatic carboxylic acid whereas sodium benzoate is the sodium salt of benzoic acid. Summary – Benzoic Acid vs Sodium Benzoate Both these compounds are important as food preservatives. Furthermore, both these compounds appear as white crystalline solids, but benzoic acid appears as needle-like structures while sodium benzoate is often a powdered solid. But for sodium benzoate, the melting point is a very high value – 410 ☌. The melting point of benzoic acid solid is about 122.41 ☌. So, this is another difference between benzoic acid and sodium benzoate. Moreover, benzoic acid is poorly water-soluble at room temperature, but if we heat the compound it becomes more water-soluble however, sodium benzoate is water-soluble at room temperature. However, both these are organic compounds because both these compounds have an aromatic benzene ring, substituted with a carbonyl group. What is the Difference Between Benzoic Acid and Sodium Benzoate? The major application of this compound is its use as a food preservative. Some rich sources are among vegetables and fruits. Usually, sodium benzoate is present in many food products along with benzoic acid. But, commercially, we can produce it also by partial oxidation of toluene in the presence of oxygen. This production method involves the reaction between sodium hydroxide and benzoic acid. We can produce it via the neutralization reaction of benzoic acid. ![]() Sodium benzoate is the sodium salt of benzoic acid having the chemical formula C6H5COONa. Benzoic acid can be naturally found in some fruits such as berries. This means it can prevent fungi growth in food. Therefore, electrophiles can react with the aromatic ring.īenzoic acid is a fungistatic compound that is widely used as a food preservative. Carboxylic acid can provide the aromatic ring with pi electrons. The boiling point of benzoic acid is given as 249.2 ☌, but at 370 ☌, it decomposes.īenzoic acid can undergo electrophilic aromatic substitution due to the electron-withdrawing property of the carboxylic group. At room temperature and pressure, benzoic acid is a white crystalline solid. ![]()
