Define conductivity and molar conductivity for the solution of an electrolyte
Conductivity:
Conductivity is a measure of a material’s ability to conduct an electric current. In the context of solutions of electrolytes, it refers to the ability of an electrolyte solution to conduct electricity. The unit of conductivity is Siemens per meter (S/m) or mhos/cm.
Molar Conductivity:
Molar conductivity is the conductivity of a solution containing one mole of electrolyte at a specific concentration in a specific volume. It is expressed in siemens per meter squared per mole per liter (S m² mol⁻¹ L⁻¹) or mhos cm² mol⁻¹.
In simple terms, conductivity gives us information about how well a solution can conduct electricity, while molar conductivity focuses on the conductance of a specific concentration of an electrolyte solution. Conductivity is influenced by the concentration of ions in the solution, temperature, and the nature of the electrolyte. Molar conductivity, on the other hand, helps in determining the overall conducting power of a specific quantity of an electrolyte solution.
