Hint: Here we will proceed by defining the term distilled water and good conductors. Then we will see how many numbers of ions and what type of impurities are there in distilled water to know whether it is a good conductor or not and hence to obtain the correct answer. Complete answer: Distilled water: Distilled water is water that has been boiled into vapour and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. Good conductors: Good conductors are the materials which allow electricity to pass through them easily. Poor conductors: A poor conductor is a material that has low heat or electrical conductivity. Some examples of poor conductors are rubber, plastics and gases. In distilled water, there are no impurities, there are no ions, there are only neutral (no charge) water molecules and these neutral molecules don't have charge, so distilled water does not conduct electricity. Distilled water has had all of the minerals removed from it which makes it an insulator rather than a conductor. Distilled water is a poor conductor of electricity because it does not contain any dissolved salts in it which can provide it ions to conduct electricity Hence, distilled water is not a good conductor of electricity. Thus, the correct option is B. False Note: Conductors are the materials or substances which allow electricity to flow through them. They conduct electricity because they allow electrons to flow easily inside them from atom to atom. Also, conductors allow the transmission of heat or light from one source to another. Pure water is not a good conductor of electricity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10×10−6W−1m−1(20ds/m) . Because the electrical current is transported by ions in solution, the conductivity increases as the concentration of ions increases.
