Which of the following compounds is a strong electrolyte? A)methane, CH₄ B)methanol, CH₃OH C)ammonia, NH₃ D)hydrofluoric acid, HF E)potassium chloride, KCl

Question

Quizplus · Accepted Answer

Potassium chloride (KCl) is an ionic compound that dissociates completely in water, producing ions (K+ and Cl-) that conduct electricity. Therefore, KCl is a strong electrolyte. The other options are not strong electrolytes. Methane (CH4) is a nonpolar covalent compound that does not dissociate in water or conduct electricity. Methanol (CH3OH) is a polar covalent compound, but it only partially dissociates in water and is considered a weak electrolyte. Ammonia (NH3) is a polar covalent compound that can form hydrogen bonds with water but it is also a weak electrolyte. Hydrofluoric acid (HF) is a polar covalent compound that dissociates to a small extent in water but it is also a weak electrolyte.
