Can Distilled Water Conduct Electricity? Overview of the Conductivity of Distilled Water
Distilled water does not conduct electricity because it is pure and lacks sufficient ionic concentration, diversity and potential to support any significant flow of electric current. This article answers the question; “can distilled water conduct electricity?” among others, as outlined below;
Is Distilled Water A Conductor?
Distilled water is a conductor of electricity, but not a GOOD conductor. It is a very poor conductor due to its low ionic content and ionization potential.
*Distilled water, also known as deionized water, is water that has been purified through a process of distillation. During distillation, impurities and minerals are removed, resulting in water that is almost entirely pure H2O molecules. This purity is what makes distilled water a poor conductor of electricity.
*In order for a substance to conduct electricity, it must contain charged particles, or ions, that can move freely within the material. These ions carry electric charge and allow for the flow of electric current. In the case of distilled water, the low ionic content means that there are very few ions present to facilitate the flow of electricity.
*For distilled water to conduct electricity with efficiency, it must be ‘contaminated’ with ionic substances like salts, acids, or alkalis. These substances dissociate in water, releasing ions that can carry electric charge. When dissolved in distilled water, these ionic substances increase the concentration of ions and enhance its conductivity.
*The presence of ions in water is crucial for its ability to conduct electricity. In the case of distilled water, the lack of ions limits its conductivity. The ionization potential of H+ and OH- ions in distilled water is also low, further reducing its ability to conduct electricity.
*It is important to note that even though distilled water is a poor conductor, it is not an insulator. An insulator is a material that does not conduct electricity at all. Distilled water still contains a small number of ions, albeit at a very low concentration. This means that it can still conduct electricity to some extent, although the conductivity is significantly lower compared to other substances.
Why Doesn’t Distilled Water Conduct Electricity?
Although it contains approximately 10-7 M each of H+ and OH- ions, distilled water does not conduct electricity to any significant degree. There are several reasons why distilled water doesn’t conduct electricity, include its purity, and low ionic concentration, among other factors discussed below;
1. It is Pure
Distilled water is highly pure and lacks conductive ionic species or impurities. During the distillation process, impurities and minerals are removed, resulting in water that is almost entirely pure H2O molecules. This high level of purity means that there are very few ions present in distilled water to facilitate the flow of electricity. Without the presence of ions, the conductivity of distilled water is significantly reduced.
2. Ionic Concentration is Low
In order for a substance to conduct electricity, it must contain charged particles or ions that can move freely within the material. These ions carry electric charge and allow for the flow of electric current. However, the low ionic content in distilled water means that there are very few ions available to carry electric charge. As a result, the conductivity of distilled water is greatly diminished.
3. H+ and OH- ions in Distilled Water Both Have Low Ionization Potentials
The ionization potential refers to the energy required to remove an electron from an atom or molecule, resulting in the formation of ions. In the case of distilled water, both the H+ and OH- ions have low ionization potentials. This means that it takes very little energy to remove an electron from these ions, resulting in a low concentration of ions in the water. The low concentration of ions further reduces the ability of distilled water to conduct electricity.
4. Metallic Ions of Salts, Acids, and/or Bases are Absent
For distilled water to conduct electricity efficiently, it must be “contaminated” with ionic substances like salts, acids, or bases. These substances dissociate in water, releasing ions that can carry electric charge. When dissolved in distilled water, these ionic substances increase the concentration of ions and enhance its conductivity. However, distilled water does not naturally contain these metallic ions, which limits its ability to conduct electricity.
5. Low Acidity and Salinity
The acidity and salinity of water can also affect its conductivity. Distilled water has a neutral pH and low salinity, which means it has a low concentration of ions. This low ion concentration further hinders the flow of electric current through the water. In contrast, water with higher acidity or salinity, such as seawater, has a higher concentration of ions and therefore exhibits greater conductivity.
Why Does Distilled Water Not Conduct Electricity, Whereas Rainwater Does?
Distilled water and rainwater have different electrical conductivity properties due to their varying compositions. Distilled water, which is highly pure, lacks conductive ionic species or impurities, while rainwater contains ions dissolved from atmospheric impurities, rooftops, and rocks, among others. This fundamental difference in composition is what makes distilled water non-conductive, while rainwater can conduct electricity to some extent.
*Distilled water is highly pure and lacks conductive ionic species/impurities. During the distillation process, impurities and minerals are removed, resulting in water that is almost entirely pure H2O molecules. This high level of purity means that there are very few ions present in distilled water to facilitate the flow of electricity. Without the presence of ions, the conductivity of distilled water is significantly reduced.
*On the other hand, rainwater is rich in ions dissolved from various sources. As rainwater falls through the atmosphere, it can pick up impurities such as dust, pollutants, and gases. These impurities can react with the water molecules, forming ions that can conduct electricity. Additionally, rainwater can also dissolve ions from rooftops, rocks, and other surfaces it comes into contact with. These dissolved ions increase the conductivity of rainwater compared to distilled water.
*The presence of ions in rainwater allows it to conduct electricity to some extent. When an electric field is applied to rainwater, the ions can move freely within the water, carrying electric charge and allowing for the flow of electric current. However, it’s important to note that the conductivity of rainwater is still relatively low compared to other conductive solutions, such as saltwater or electrolytes.
*Generally, the difference in electrical conductivity between distilled water and rainwater can be attributed to their respective compositions. Distilled water, being highly pure and lacking ions, does not conduct electricity efficiently. On the other hand, rainwater contains dissolved ions from various sources, allowing it to conduct electricity to some degree. Understanding the composition and properties of these types of water is important in various applications, such as in electronics, chemistry, and environmental studies.
*To explore the conductivity of different types of water, it is essential to consider factors such as pH, salinity, and the presence of impurities. These factors can influence the conductivity of water and determine its suitability for specific purposes.
