Ionic compounds dissolve in water because water molecules can surround and separate the ions, allowing them to move freely. In organic solvents, the ions are not effectively separated, so they remain insoluble.
Why are ionic compounds soluble in water but not in organic solvents?
Ionic compounds have strong electrostatic forces between cations and anions. Breaking these bonds requires a significant amount of energy, resulting in high melting points.
Metals lose electrons to form cations, while non-metals gain electrons to form anions. The electrostatic attraction between these oppositely charged ions results in the formation of an ionic bond.
An amphoteric oxide is a metal oxide that can react with both acids and bases to form salts and water. Examples include aluminum oxide (Al₂O₃) and zinc oxide (ZnO).
