Here's why:
* Ionic Compounds: These compounds are formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).
* Aqueous Solution: When an ionic compound dissolves in water, the ions dissociate (separate) from each other and become surrounded by water molecules.
* Electrical Conductivity: These free ions in solution can move, carrying an electric charge. This movement of charged particles allows the solution to conduct electricity.
Examples of Electrolytes:
* Sodium chloride (NaCl): Dissolves into Na+ and Cl- ions.
* Potassium hydroxide (KOH): Dissolves into K+ and OH- ions.
* Copper sulfate (CuSO4): Dissolves into Cu2+ and SO42- ions.
Note: Not all ionic compounds are electrolytes. Some ionic compounds are only slightly soluble in water, meaning they don't produce enough free ions to conduct electricity effectively.
