Is it right or wrong if (molar conductance /equivalent conductance at ...
Explanation:
There is a relationship between molar conductance, equivalent conductance at infinite dilution, and the degree of dissociation.
Molar Conductance and Equivalent Conductance at Infinite Dilution:
- Molar conductance is the conductance of a solution containing one mole of an electrolyte.
- Equivalent conductance at infinite dilution is the sum of conductance of individual ions in a solution when the concentration tends to zero.
Degree of Dissociation:
- The degree of dissociation is the fraction of the total number of moles of an electrolyte that dissociates into ions in a solution.
Relationship:
- The molar conductance divided by the equivalent conductance at infinite dilution is equal to the degree of dissociation. This relationship is based on the Kohlrausch's law of independent migration of ions.
- The formula for this relationship is: α = Λm/Λ∞
Explanation of the Relationship:
- Molar conductance represents the total conductance in a solution, while equivalent conductance at infinite dilution represents the conductance of individual ions.
- The degree of dissociation is a measure of how much of the electrolyte has dissociated into ions in the solution.
- When the molar conductance is divided by the equivalent conductance at infinite dilution, it gives the degree of dissociation, which shows the extent of dissociation of the electrolyte.
Conclusion:
- Therefore, if (molar conductance / equivalent conductance at infinite dilution) is equal to the degree of dissociation, it is correct based on the relationship between these parameters in electrolyte solutions.
