Here's why:
* Water is polar: Water molecules have a slightly positive end (near the hydrogen atoms) and a slightly negative end (near the oxygen atom). This makes them attracted to ions.
* Ions are charged: When ionic compounds dissolve, they separate into positively charged cations and negatively charged anions.
* Attraction and Surroundings: The positive ends of water molecules surround the anions, while the negative ends of water molecules surround the cations. This attraction helps to overcome the forces holding the ions together in the solid and allows them to disperse in the water.
Essentially, the water molecules form a sort of "hydration shell" around each ion, weakening the ionic bonds and allowing the compound to dissolve.
