검증된 단계별 안내1
Understand what a strong electrolyte is: a substance that completely dissociates into ions when dissolved in water, resulting in a solution that conducts electricity very well.
Analyze each compound given: NH3 (ammonia) is a weak base and does not fully ionize in water; it mostly remains as molecules.
C6H12O6 (glucose) is a molecular compound that dissolves but does not ionize, so it does not produce ions to conduct electricity.
CH3COOH (acetic acid) is a weak acid that partially ionizes in water, meaning it only partially dissociates into ions.
NaCl (sodium chloride) is an ionic compound that completely dissociates into Na+ and Cl- ions in water, making it a strong electrolyte.
