Here's why:
* Electrolytes are substances that conduct electricity when dissolved in water. This conductivity is due to the presence of free ions, which are charged particles that can move freely.
* When an electrolyte dissolves in water, it breaks down into its constituent ions. For example, table salt (NaCl) dissolves in water to form sodium ions (Na+) and chloride ions (Cl-).
* The presence of these free ions allows the solution to conduct electricity.
Examples of electrolytes:
* Salts (like sodium chloride, potassium chloride)
* Acids (like hydrochloric acid, sulfuric acid)
* Bases (like sodium hydroxide, potassium hydroxide)
Important Note: Not all compounds are electrolytes. Some compounds, like sugar (sucrose), do not dissociate into ions when dissolved in water and are therefore called nonelectrolytes.
