Final answer:
An electrolyte is a substance that conducts electricity when dissolved in water. Strong electrolytes have many ions in solution and are good conductors, while weak electrolytes have a low concentration of ions and conduct electricity less effectively. Non-electrolytes do not conduct electricity at all.
Step-by-step explanation:
An electrolyte is a substance that conducts electricity when dissolved in water. A strong electrolyte contains many ions in solution, making it a good conductor of electricity. Examples of strong electrolytes include sodium chloride (NaCl) and hydrochloric acid (HCl). A weak electrolyte, on the other hand, has a low concentration of ions in solution and conducts electricity less effectively. Acetic acid (CH3COOH) is an example of a weak electrolyte. Non-electrolytes do not conduct electricity at all because they do not release any ions when dissolved in water. Examples of non-electrolytes include ethanol (C2H5OH) and glucose (C6H12O6).
