Which is more soluble benzoic acid or sodium benzoate?
2 Sodium benzoate Although undissociated benzoic acid is the more effective antimicrobial agent for preservation purposes, sodium benzoate is used preferably, as it is about 200 times more soluble than benzoic acid.
Is benzoic acid soluble in methylene chloride?
Caffeine and benzoic acid are both soluble in DCM, but cellulose is not.
Why is sodium benzoate soluble in water and benzoic acid insoluble?
It is because the ionic bond between the sodium and the benzoic acid breaks in water, leading to dissociation. It is because the ionic bond between the sodium and the benzoic acid breaks in water, leading to dissociation.
Which is more soluble in water methyl benzoate or benzoic acid?
It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents. Methyl benzoate has a pleasant smell, strongly reminiscent of the fruit of the feijoa tree, and it is used in perfumery….CHEBI:72775.

What is the solubility of sodium benzoate in water?
Sodium benzoate is highly soluble in water (66 g/100 mL at 20 °C). (9) This dissolution is endothermic: the enthalpy of solution is +2.40 kJ mol–1 for crystallized sodium benzoate.
Why is benzoic acid more soluble in methylene chloride?
Benzoic acid is a polar protic compound due to the presence of the polar protic -COOH group. Hence, it is expected that benzoic acid to be soluble in both water dichloromethane by means of polar intermolecular forces, e.g., dipole-dipole interaction and hydrogen bonding.
Is sodium benzoate water soluble?
What does sodium benzoate dissolve in water?
Which compound is more soluble in water?
Among all the four chemical compound ethylene glycol(OH – CH2 – CH2 – OH) has two hydroxyl group and both are available for hydrogen bonding with water. As a result water solubility of ethylene glycol is high.
