Hint: An insulator is a material in which the electrons cannot move freely or we can say that the electrons in the insulator are bounded tightly so that the electricity cannot pass through them. Some common types of insulators are wood, plastic, and ceramics.
Complete step by step answer:
Pure water is completely deionized water, which means that pure water does not contain any ions.
Now, the electricity requires a movement of charge throughout and across the liquid, so that it can travel through the water.
Pure water does not conduct electricity, because it contains only the water that is not able to break down into ions as the dissociation of the ions of this water is weak.
Also, pure water does not consist of calcium and dissolved magnesium salts that are good conductors of electricity. Therefore, pure water is also a bad conductor of electricity. Hence, pure water is an insulator.
Hence, the above statement is true.
Note:
Normal water is a good conductor of electricity because it contains charged ions, calcium, magnesium salts, and other impurities that allow the current to through them. That is why, everyone said that water and electricity form a bad pair because when a person comes in contact with this pair, it will give him a shock which can be dangerous.
In the distilled water, there are no impurities present and thus there will be no ions. In fact, distilled water contains neutral molecules and these neutral molecules do not allow a charge to pass. Therefore, distilled water is also a bad conductor of electricity.
