Best Answer: A nonelectrolyte is a substance that doesn't split up into ions when dissolved into solution. LiF is an ionic compound that is soluble in water, completely splitting up into ions. HCl is a strong acid, completely splitting up into ions when dissolved in water. Acetic acid is a weak acid. When dissolved in water, a small percentage of it splits into ions, so it still is an electrolyte. Sucrose does NOT split up into ions when dissolved in water so it is a nonelectrolyte.
â¢Oil and water do NOT mix. o Nonpolar substances such as fat dissolve in nonpolarsolvents such as benzene because the forces of attraction are too weak to prevent the particles from freely intermingling.
