What process allows water to dissolve ionic compounds?

Water's ability to dissolve ionic compounds is primarily due to its polar nature, which allows for effective interactions with the ions in the ionic compound. Water molecules have a partial negative charge on the oxygen atom and a partial positive charge on the hydrogen atoms, resulting in a polar molecule. When an ionic compound is introduced to water, the polar water molecules surround the individual ions.

The positive side of the water molecule (the hydrogen atoms) attracts the negative ions (anions), while the negative side (the oxygen atom) attracts the positive ions (cations). This interaction leads to the formation of hydration shells around the ions, effectively pulling them away from the lattice structure of the ionic compound and into solution. This process not only stabilizes the ions in the solution but also facilitates the dissolution of the ionic compound.

Hydrolysis of the ionic bond is less relevant here as it typically refers to reactions where water breaks down the compound rather than simply dissolving it. Similarly, evaporation of water molecules primarily refers to the physical process of liquid turning into vapor, which does not directly contribute to the dissolution of ionic compounds. Freezing point lowering is a colligative property that occurs when a solute is added to a solvent, but it does not explain the mechanism by
