As a subject matter expert in the field of physical sciences, I can provide you with an in-depth explanation of the electrical conductivity of water.
Water, in its purest form, is actually a very poor conductor of electricity. This is because pure water, which is water that has been distilled or deionized, lacks any significant concentration of ions. Ions are charged particles that are necessary for the flow of electric current. Without ions, there are no charge carriers to facilitate the movement of electricity through the substance.
However, the water that we encounter in our daily lives is rarely pure. Tap water, for example, contains various dissolved minerals and impurities. Among these, calcium and magnesium salts are common. These dissolved salts dissociate into their respective ions when in solution, thereby increasing the water's ability to conduct electricity. The presence of these ions provides the necessary charge carriers for electricity to flow.
The conductivity of water can also be influenced by other factors such as temperature, pH, and the presence of other dissolved substances. For instance, as the temperature of water increases, its ability to conduct electricity generally improves because the movement of ions is enhanced at higher temperatures.
Furthermore, the pH of water can affect its conductivity. Water that is more acidic or more basic can have a higher concentration of hydrogen ions (H+) or hydroxide ions (OH-), respectively, which can also contribute to its electrical conductivity.
It is important to note that the conductivity of water is still relatively low compared to metals, which are excellent conductors of electricity. Metals have a lattice structure with free electrons that can move easily and thus facilitate the flow of electric current. In contrast, water's conductivity is dependent on the number and mobility of its dissolved ions.
In practical applications, water's conductivity is often measured using a device called a conductivity meter. This tool can provide a quantitative measure of the water's ability to conduct electricity, which can be useful in various industries, such as water treatment, agriculture, and environmental monitoring.
In summary, while pure water is a poor conductor of electricity, the presence of dissolved ions in tap water or other impure forms of water significantly increases its conductivity. The conductivity can be influenced by factors such as temperature, pH, and the concentration of dissolved substances.

Tap water conducts electricity since there are small amounts of calcium and magnesium salts dissolved in it, pure water ( distilled or deionised) has nothing at all in it that can conduct electricity.
