Answer
ions
molecules
Step-by-step explanation
An aqueous solution of table salt conducts electricity because it has ions in it that have the freedom to move about in the solution. These ions are produced when sodium chloride dissolves in pure water to produce sodium (Na+) and chloride ions (Cl–).
On the other hand, an aqueous solution of sugar does not conduct an electric current because sugar (C12H22O11) dissolves in water to produce molecules. These sugar molecules are usually neutral (not charged), and so are unable to move to the opposite ends of the electrodes like the ions.
