What Is Specific Conductance?

Are you curious to know what is specific conductance? You have come to the right place as I am going to tell you everything about specific conductance in a very simple explanation. Without further discussion let’s begin to know what is specific conductance?

In the world of chemistry and physical sciences, understanding the behavior of substances in solution is crucial. One important property that helps us comprehend the conductivity of a solution is specific conductance. Specific conductance, also known as specific conductivity or conductivity, is a fundamental concept that measures the ability of a solution to conduct an electric current. In this blog, we will delve into the concept of specific conductance, its significance, and how it is measured.

What Is Specific Conductance?

Specific conductance is a measure of the ability of a solution to carry an electrical current. It is influenced by the concentration and mobility of charged particles, such as ions, present in the solution. When an electric potential difference (voltage) is applied across two electrodes immersed in a solution, the specific conductance determines how easily the current flows through the solution.

The unit of specific conductance is Siemens per meter (S/m) or mhos per centimeter (mho/cm). It represents the conductance of a 1-meter-long column of solution with a 1-square-meter cross-sectional area. Conductance is the reciprocal of resistance, so higher values of specific conductance correspond to greater electrical conductivity.

Factors Affecting Specific Conductance:

Several factors influence the specific conductance of a solution:

  1. Concentration of Charged Particles: The presence of ions, which are charged particles, significantly affects the specific conductance. Solutions with higher concentrations of ions tend to have higher conductivities. This is because the ions act as charge carriers and facilitate the flow of electric current.
  2. Temperature: Temperature plays a crucial role in specific conductance. Generally, as the temperature increases, the specific conductance of a solution also increases. This behavior can be attributed to the increased mobility of ions at higher temperatures.
  3. Nature of the Solvent: The nature of the solvent in which ions are dissolved can impact specific conductance. Different solvents have different dielectric constants and viscosities, which influence the mobility and interactions of ions, thereby affecting conductance.

Measuring Specific Conductance:

Specific conductance is typically measured using a conductivity meter, also known as a conductometer or conductivity probe. These devices consist of two or more electrodes, usually made of a noble metal like platinum, and are connected to an electrical circuit. The electrodes are immersed in the solution whose conductance is to be measured.

The conductivity meter applies a small electric potential difference across the electrodes and measures the resulting current. By knowing the geometry of the electrodes and the distance between them, along with the measured current, the specific conductance of the solution can be determined.

Applications Of Specific Conductance:

Specific conductance has numerous practical applications in various fields:

  1. Water Quality Assessment: Conductivity measurements are widely used in assessing the quality and purity of water. High specific conductance can indicate the presence of dissolved salts or other impurities.
  2. Industrial Processes: Specific conductance is crucial in industries where monitoring and controlling the concentration of ions is vital. For example, in the production of chemicals, pharmaceuticals, and food products, specific conductance measurements help maintain desired process conditions.
  3. Environmental Studies: Conductivity measurements are employed in environmental studies to evaluate the salinity and pollution levels of water bodies. It provides valuable information about the health and viability of aquatic ecosystems.


Specific conductance serves as a powerful tool for understanding the electrical conductivity of solutions. By measuring the ability of a solution to conduct an electric current, we can gain insights into its composition, concentration, and purity. Whether it is for scientific research, industrial applications, or environmental monitoring, specific conductance plays a significant role in a wide range of fields. Embracing this concept enables us to better comprehend the behavior of solutions and make informed decisions in various domains.


What Is Meant By Specific Conductance?

Specific conductivity (better known as conductivity) is the measure of the ability of that material to conduct electricity. It is represented by the symbol “К”. Hence, by definition, G = 1 R.

What Is Specific Conductance With Example?

Let’s consider an Example such that the distance between the two Electrodes is 1 cm and the area of cross-sectIon A is 1 cm. Therefore, k = G. Thus, the Conductance of two Electrodes, 1 cm apart with cross-sectIon of 1cm square can be defined as Specific Conductance.

What Is Specific Conductance And Molar Conductance Class 12?

Specific conductance = Conductance × cell constant. Molar conductance: It is defined as the conductance due to 1 mol of the electrolyte present in volume V of the solution. For electrolyte concentration =c M. Molar conductivity, Λm=cκ It has a unit of Sm2mol−1.

What Is Specific Conductance And Equivalent Conductance?

Units of specific conductance are Ω−1cm−1 or mho cm−1 or Siemens m−1 (in SI system). Equivalent conductivity The conducting power of all the ions produced by dissolving 1g equivalent of an electrolyte in a given soluton is known as its equivalent conductivity. It is represented by λeq.
