* Ionic nature: Sodium benzoate is an ionic compound, formed from the sodium cation (Na+) and the benzoate anion (C7H5O2-). The strong electrostatic attraction between these oppositely charged ions forms a stable ionic bond.

* Polarity: Both sodium and benzoate ions are polar. Water is also a polar solvent, meaning its molecules have a positive and a negative end. The positive end of water molecules is attracted to the negative end of the benzoate ion, while the negative end of water molecules is attracted to the positive end of the sodium ion. This interaction, known as dipole-dipole interaction, helps dissolve the ionic compound.

* Hydrogen bonding: The benzoate anion can also participate in hydrogen bonding with water molecules. The oxygen atoms in the benzoate ion can form hydrogen bonds with the hydrogen atoms in water molecules. This further enhances the solubility of sodium benzoate in water.

These factors work together to overcome the strong ionic bond in sodium benzoate and allow it to dissolve readily in water.
