What Is Equivalent Conductance?

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

In the realm of chemistry, the concept of equivalent conductance plays a pivotal role in understanding the electrical conductivity of electrolytes. Equivalent conductance is a parameter that sheds light on the ability of an electrolyte to conduct electricity. This comprehensive guide aims to demystify the term, exploring its definition, formula, measurement, and significance in the study of conductivity.

What Is Equivalent Conductance?

Equivalent conductance is a measure of the ability of an electrolyte to conduct an electric current. It is expressed in terms of equivalents, which are a measure of the chemical activity of a substance in a reaction. Equivalent conductance is particularly significant when studying the behavior of electrolytes in solution and their impact on electrical conductivity.

What Is Equivalent Conductance Formula?

The formula for calculating equivalent conductance (Λeq) is given by:

Λeq = κ/n

Here,

  • Λeq is the equivalent conductance,
  • κ is the conductivity of the solution in siemens per centimeter (Scm−1),
  • n is the concentration of the electrolyte in equivalents per unit volume.

What Is Equivalent Conductance Class 12?

In Class 12 chemistry, students encounter the concept of equivalent conductance as part of their studies on electrolytic conductance. Understanding how to calculate and interpret equivalent conductance is crucial for mastering this aspect of electrochemistry.

What Is Molar Conductance?

Molar conductance (Λm) is another related term, representing the conductance of all the ions produced by one mole of an electrolyte in a solution. It is connected to equivalent conductance through the formula:

Λm = Λeq/Equivalent Mass

Equivalent Conductance Unit

The unit of equivalent conductance is siemens per centimeter equivalent (

Scm2≡−1). This unit emphasizes the relationship between conductance, concentration, and the chemical activity of the electrolyte.

Measurement Of Equivalent Conductance

The measurement of equivalent conductance involves experimental techniques where the conductivity of a solution is determined using a conductivity cell. The concentration of the electrolyte and its equivalent conductance are then used to calculate the specific conductance and subsequently the molar or equivalent conductance.

Equivalent Conductance Symbol Pronunciation

The symbol for equivalent conductance (Λeq) is pronounced as “Lambda equivalent.” This symbol is widely used in chemical literature and discussions to represent this specific conductance parameter.

Equivalent Conductance At Infinite Dilution

Equivalent conductance at infinite dilution (Λeq0) is a crucial parameter representing the limiting value of equivalent conductance as the concentration of the electrolyte approaches zero. It provides insights into the behavior of electrolytes in extremely dilute solutions.

Conclusion

In summary, equivalent conductance is a vital parameter in electrochemistry, offering insights into the electrical conductivity of electrolytes. It is calculated based on the conductivity of the solution and the concentration of the electrolyte in equivalents per unit volume. Understanding the concept, its formula, and its measurement techniques is essential for students and researchers delving into the complexities of chemical conductivity. As a key aspect of electrochemical studies, equivalent conductance plays a significant role in enhancing our comprehension of the behavior of electrolytes in solution.

FAQ

What Is Equivalent Conductance In Simple Words?

Equivalent Conductivity is defined as the conducting power of all the ions produced by dissolving one gram equivalent of an electrolyte in solution.

What Is Equivalent And Molar Conductance?

The conductivity of a volume of solution containing one equivalent of an electrolyte is called equivalent conductivity. The conductance property of a solution containing one mole of electrolyte, or a function of a solution’s ionic strength or salt concentration, is known as molar conductivity.

What Is The Si Unit For Equivalent Conductance?

It is equal to the product of specific conductance (k) of the solution and the volume (V) of the solution that contains one gram equivalent of the electrolyte. The unit of specific conductance k is Siemens / m. so,The required equivalent conductance unit is Siemens m^2/equivalent.

What Is Equivalent Conductivity Law?

Kohlrausch’s law states that the equivalent conductivity of an electrolyte at infinite dilution is equal to the sum of the conductances of the anions and cations. If a salt is dissolved in water, the conductivity of the solution is the sum of the conductances of the anions and cations.
