As an expert in the field of physical sciences, I am often asked about the electrical properties of water. The concept of water's conductivity is a nuanced one, and it's important to understand the factors that influence it.
Firstly, it's crucial to clarify that pure water, which is water that has been distilled or deionized to remove impurities, is a poor conductor of electricity. This is because pure water lacks the free ions that are necessary for electrical conductivity. Ions are atoms or molecules that have gained or lost electrons, and they are the charge carriers in a solution. In pure water, the concentration of ions is very low, as it is a covalent compound and does not readily dissociate into ions.
However, the statement that "Water is a terrible conductor of electricity" is not entirely accurate. While it's true that pure water is a good insulator, the conductivity of water can be significantly enhanced by the presence of dissolved salts and other ionic compounds. When these substances dissolve in water, they dissociate into their constituent ions, increasing the water's ability to conduct electricity.
The solubility of ionic compounds in water is an important factor in this context. Water is a great ionic solvent, which means it can dissolve many ionic compounds easily. For example, when table salt (sodium chloride) dissolves in water, it breaks down into its constituent ions, sodium (Na+) and chloride (Cl-), which are then free to move about in the solution. This movement of ions is what allows the solution to conduct electricity.
The concentration of dissolved ions in water is directly related to its conductivity. The higher the concentration of ions, the better the water will conduct electricity. This is why seawater, which contains a high concentration of dissolved salts, is a much better conductor than pure water.
Additionally, the temperature of the water can also affect its conductivity. As the temperature increases, the kinetic energy of the water molecules and the dissolved ions increases, leading to more frequent collisions and a higher rate of ion mobility. This results in an increase in the water's electrical conductivity.
In practical terms, the conductivity of water is measured using the specific conductance or conductivity meter, which provides a measure of the water's ability to conduct an electrical current. The unit of measurement for specific conductance is the Siemens per meter (S/m), and for conductivity, it is microsiemens per centimeter (µS/cm).
In summary, while pure water is a good insulator, the presence of dissolved ions can turn it into a conductor. The conductivity of water is influenced by the concentration of dissolved ions, the type of ions present, and the temperature of the water. Understanding these factors is essential for various applications, such as in the design of electrical systems, water treatment processes, and environmental monitoring.

Water is a terrible conductor of electricity. Pure water is actually a good insulator. However, water is a great ionic solvent: liquid in which ionic compounds can dissolve easily. It's those dissolved ions that can conduct well - and when water contains many dissolved ions, those ions make a good conductor.
