As an expert in the field of physical sciences, I can provide a detailed explanation of why water is not a good conductor of electricity. The ability of a substance to conduct electricity is primarily determined by the presence of charge carriers within the material. In the case of water, the situation is quite complex due to its molecular structure and the nature of its interactions.
Water, in its pure form, is composed of neutral molecules, H2O, which do not carry a net electrical charge. However, water can become a conductor under certain conditions. This happens when impurities or dissolved substances are present that can dissociate into ions. These ions can then move freely in the water, allowing it to conduct electricity.
The reference to distilled water is particularly pertinent. Distilled water is water that has been purified to remove impurities and dissolved substances. In distilled water, there are no impurities and therefore no ions. This lack of ions means that there are no free charge carriers available to move through the water and conduct electricity. The neutral water molecules themselves do not have a charge and thus cannot facilitate the flow of electricity.
However, it's important to note that even in distilled water, there can be a very slight conductivity due to the self-ionization of water. This is a process where a very small number of water molecules can dissociate into H+ and OH- ions. The self-ionization constant for water, known as the ion product of water (Kw), is very low, approximately \(1 \times 10^{-14}\) at 25°C. This means that the concentration of H+ and OH- ions in pure water is very low, and thus the conductivity is minimal.
In contrast, when water contains impurities, such as salts or other dissolved substances, these can increase the conductivity significantly. For example, when table salt (sodium chloride) is dissolved in water, it dissociates into Na+ and Cl- ions, which are free to move and carry an electrical charge. This makes the water a much better conductor of electricity.
The conductivity of water can also be affected by temperature. As the temperature increases, the kinetic energy of the water molecules increases, which can lead to more frequent collisions and a higher chance of ionization, thus increasing the conductivity.
In summary, water is not a good conductor of electricity because, in its pure form, it lacks free charge carriers. Distilled water, being free of impurities and ions, has minimal conductivity. The presence of impurities or dissolved substances that can dissociate into ions increases the water's conductivity. Additionally, temperature can play a role in affecting the conductivity of water.

In distilled water, however, there are no impurities and therefore no ions. There are only neutral molecules, and these neutral molecules don't have any charge. For that reason, distilled water is unable to conduct electricity.
