Here's why:

* Electrolytes are substances that conduct electricity when dissolved in water or melted.

* Ions are atoms or molecules that have gained or lost electrons, giving them a net positive or negative charge.

* When electrolytes dissolve in water, the ions separate and are free to move, carrying an electrical current.

Non-electrolytes are substances that do not conduct electricity when dissolved in water or melted. They are typically composed of molecules that do not dissociate into ions in solution.

Examples:

* Electrolytes: Table salt (NaCl), potassium chloride (KCl), sodium hydroxide (NaOH), acids (like hydrochloric acid, HCl), and bases (like calcium hydroxide, Ca(OH)2)

* Non-electrolytes: Sugar (C12H22O11), ethanol (C2H5OH), and urea (CH4N2O)
