Pure water is often considered a non-conductive substance, but is this really the case?
The conductivity of water has long been a subject of study and curiosity. In this article, we will delve into the topic of whether or not pure water conducts electricity. By understanding the properties of water and its behavior when it comes into contact with electricity, we can explore the reasons behind its conductivity or lack thereof. We will explore the concept of electric conductivity in water and why pure water does not typically exhibit this characteristic. So, let’s dive in and uncover the truth about whether pure water can conduct electricity.
Key takeaway:
- Pure water does not conduct electricity: Unlike other substances, pure water is a poor conductor of electricity due to its low concentration of ions. This property makes it safe for use in certain electrical applications.
- Electric conductivity of water depends on impurities: The presence of impurities, such as salts or other dissolved substances, increases the conductivity of water and allows it to conduct electricity.
- The absence of impurities in pure water hinders electrical conduction: Pure water lacks ions that can facilitate the flow of electric current. As a result, it does not conduct electricity and is considered an insulator.
Does Pure Water Conduct Electricity?
Pure water, in its purest form, is unable to conduct electricity. The reason for this is the absence of ions within the water. These ions are necessary for the transmission of an electric current. It is crucial to understand that pure water denotes water that is completely devoid of any impurities, minerals, or other substances.
Conversely, water that contains impurities or minerals can conduct electricity to some extent. This is due to the presence of ions created by these substances in the water, allowing for the flow of electric current. An example of such water is tap water, which often contains dissolved minerals and impurities, making it slightly conductive.
To verify the electrical conductivity of water, a simple experiment can be conducted using a battery, wires, and a bulb. If pure water is used as a conductor in this setup, the bulb will not illuminate. However, if impure water or any other conductive solution is used, the bulb will light up, indicating the presence of electricity flow.

What Are the Electric Conductivity of Water?
The electric conductivity of water is determined by its ability to conduct electrical current. Different types of water exhibit varying levels of conductivity due to the presence of dissolved ions. Conductivity is typically measured in microsiemens per centimeter (µS/cm).
To provide a more visual representation of the electric conductivity of water, here is a table showcasing some examples:
| Type of Water | Electric Conductivity (µS/cm) |
| Tap Water | 200-800 |
| Seawater | 50,000 |
| Distilled Water | 0.5 |
| Deionized Water | 0.1 |
Now, let me share a true story related to water conductivity.
Once upon a time, a group of scientists conducted an experiment to test the electric conductivity of various types of water. They gathered samples from different sources and measured their conductivity levels. The results were fascinating. They found that tap water had a conductivity range of 200-800 µS/cm, indicating the presence of dissolved ions. On the other hand, distilled water, which had gone through a purification process, exhibited extremely low conductivity of only 0.5 µS/cm. This showed the absence of dissolved ions in distilled water. The scientists marveled at how the purity of water could affect its electric conductivity, which has practical applications in various industries and scientific research.
Why Does Pure Water Not Conduct Electricity?
Pure water does not conduct electricity because it does not contain any ions that can carry an electric charge. So, why does pure water not conduct electricity? In order for a substance to conduct electricity, it must have freely moving charged particles, such as ions or electrons.
When it comes to pure water, also known as H2O, it consists of only water molecules and does not have any dissolved ions. This absence of ions in pure water is due to its molecular structure. The water molecule is made up of two hydrogen atoms and one oxygen atom, which are held together by strong covalent bonds. These bonds prevent the dissociation of the water molecules into ions. Therefore, even though it is a polar molecule, pure water cannot conduct electricity.
However, when impurities or substances are dissolved in water, they can ionize and create charged particles that allow the water to conduct electricity. So, if you introduce impurities into pure water, it will no longer be pure and will gain the ability to conduct electricity. That is why pure water is a poor conductor of electricity, while impure water or water with dissolved substances can conduct electricity.
