Question

Pure water is a _________ of electricity because it does not form ions.

Answer 1

Hint: As we know that usually the pure water is not available in nature. Water is the only one substance which can exist as solid state, liquid state and vapour state in the earth. And water is the most abundant and rich substance which is present in the human body. Some of the substance acts as an electrical conductor because it carries the electrical charge and the electrons will move very rapidly through the atoms by applying voltage.

Complete answer:
We know that pure water acts as a non – conductor of electricity. Because pure water does not form any pure ions.
If a substance is to transmit the electricity, the freely moving electrons or ions (charged particles) must be available in that material. But in the case of pure water, there is no availability of such types of freely moving ions or electrons. Hence, it cannot conduct electricity. So, we can say that not all the materials can act as conductors. This is because of the fact that not all the materials have free electrons. Majority, metallic substances act as conductors. Because it has free electrons.

Note:
We must remember that pure water acts as a non – conductor of electricity due to the absence of free electrons. The non – conductor material exhibits these features because it does not have extra electrons to pass the electric charge. So, it makes it very difficult to pass the charge between these materials. But in the case of a conductor, all the electrons are attached very tightly. So that it can easily pass the charge through material. For eg: iron, copper etc..
