UPSC NDA-2 – 2022
Sugar solution is not capable of conducting electricity.
For a solution to conduct electricity, it must contain free-moving ions. Solutions of ionic compounds (like Copper sulphate, Sodium chloride, Sodium hydroxide) dissociate into ions when dissolved in water, allowing them to conduct electricity. Sugar (sucrose) is a covalent compound; when it dissolves in water, it remains as neutral molecules and does not produce ions.
Electrolytes are substances that produce ions when dissolved in a solvent, making the solution electrically conductive. Non-electrolytes, like sugar, dissolve but do not ionize, and their solutions do not conduct electricity.
