Benzoic Acid (C6H5COOH) - Structure, Properties, and Uses of Benzoic Acid
Benzoic acid is not very soluble in water. However, the solubility of this compound in water increases when the temperature is increased (as is the case with most compounds). At a temperature of 0 °C, the solubility of benzoic acid in water corresponds to 1.7 grams per litre.
Benzoic acid - Wikipedia
Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic solvents for the recrystallization makes this experiment particularly safe.

A wash with sodium bicarbonate converts benzoic acid into its more water-soluble sodium benzoate form, extracting it into the aqueous layer (Figure 4.57). Additionally, the sodium bicarbonate neutralizes the catalytic acid in this reaction.

4.4 Solubility - Chemistry LibreTexts
Try dissolving benzoic acid crystals in room temperature water – you'll find that it is not soluble. As we will learn when we study acid-base chemistry in a later chapter, carboxylic acids such as benzoic acid are relatively weak acids, and thus exist mostly in the acidic (protonated) form when added to pure water.

2015年12月13日 · It would seem that the benzoate ion is relatively compatible with water, but even more attracted to calcium dication. Solubility of unionized organic molecules (like alcohols, solubilityofthings.com/water/alcohols) decreases markedly with more than 4 carbons.

2024年10月12日 · Pure benzoic acid melts at 122° C (252° F) and is very slightly soluble in water. Among the derivatives of benzoic acid are sodium benzoate, a salt used as a food preservative; benzyl benzoate, an ester used as a miticide; and benzoyl peroxide, used in bleaching flour and in initiating chemical reactions for preparing certain plastics.
