Sugar solution does not conduct electricity because it does not contain?

Answer: A sugar solution does not conduct electricity because it does not contain ions. Sugar is not an electrolyte -- a substance which ionizes when dissolved in water.

Answer: Sugar, as a non-electrolyte substance, does not produce ions when dissolved in water. A solution of sugar contains molecules of sucrose, but no ions. The absence of ions in a sugar aqueous solution makes it a non electricity conductor fluid.
