by Yuvi K - December 16, 2023

Introduction (परिचय)

Equivalent conductance (समानानुपाती प्रवाहतापन) is the measurement of conductivity per unit of charge. It is a useful tool for determining the composition of a solution, providing an indication of the number of ions present in the solution, and can be used to identify individual ions. It is also used in chemical analysis to identify different ions in a solution. In this article, we will discuss the concept of equivalent conductance and how it can be used in chemical analysis.

What is Equivalent Conductance? (समानानुपाती प्रवाहतापन क्या है?
)

Equivalent conductance (समानानुपाती प्रवाहतापन) is a measure of the conductivity of a solution, in terms of the number of ions in the solution. It is calculated by dividing the measured conductivity of the solution by the number of moles (माप गुणा) of ions in the solution. The equivalent conductance is a measure of the total number of ions present in the solution.

Calculation of Equivalent Conductance (समानानुपाती प्रवाहतापन के गणना करना)

Equivalent conductance (समानानुपाती प्रवाहतापन) can be calculated using the following formula:

Equivalent Conductivity = measured conductivity/ moles of ions

In this formula, the measured conductivity is the total conductivity of the solution, and the number of moles of ions is the total number of ions in the solution. An example calculation is as follows:

Example:

An aqueous solution is prepared with 0.2 M (molar) acetic acid. The measured conductivity of the solution is 80 S/cm (siemens per centimeter).

Equivalent Conductance |

Equivalent Conductance = measured conductivity/ moles of ions
= 80 S/cm / 0.2 mol
= 400 S/cm

Therefore, the equivalent conductance of the solution is 400 S/cm.

Types of Equivalent Conductance (समानानुपाती प्रवाहतापन के प्रकार )

Equivalent conductance (समानानुपाती प्रवाहतापन) is classified into two types:

• Molar Conductance (मापिक प्रवाहतापन): This is the measure of conductivity per mole of ions. It is expressed in units of S/cm per mole (siemens per centimeter per mole).
• Equivalent Conductance (समानानुपाती प्रवाहतापन): This is the measure of conductivity per unit of charge. It is expressed in units of S/cm per equivalent (siemens per centimeter per equivalent).

How is Equivalent Conductance Used in Chemical Analysis? (समानानुपाती प्रवाहतापन कैसे रसायन विश्लेषण में इस्तेमाल किया जाता है?)

Equivalent conductance (समानानुपाती प्रवाहतापन) is a useful tool for identifying different ions in a solution. By measuring the equivalent conductance of a solution, the number of moles (माप गुणा) of ions in the solution can be calculated. This allows chemists to identify different ions in a solution.

For example, consider an aqueous solution of 0.2 M sodium chloride. The measured equivalent conductance of the solution is found to be 400 S/cm. This indicates that there are 0.2 moles (माप गुणा) of ions in the solution. Therefore, the solution contains 0.2 moles (माप गुणा) of sodium ions and 0.2 moles (माप गुणा) of chloride ions.

Conclusion (निष्कर्ष )

Equivalent conductance (समानानुपाती प्रवाहतापन) is a useful tool for determining the composition of a solution, providing an indication of the number of ions present in the solution, and can be used to identify individual ions in a solution. It is also used in chemical analysis to identify different ions in a solution. In this article, we have discussed the concept of equivalent conductance and how it can be used in chemical analysis.
