Does glucose conduct electricity? Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
What can conduct electricity in molten? Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Does glucose conduct in solid? Then the answer is: the molecules that make up sugar connect slightly via hydrogen bonds, all electrons are bound within each molecule, there will be no exchange of electrons between molecules, hence (macro) electricity can’t pass through solid sugar.
