What are specific conductance and molar conductance?
Question: What are specific conductance and molar conductance?
Specific conductance is the electrical conductance of a solution per unit volume when the solution is at a specified temperature, usually 25°C. It is usually expressed as the reciprocal of its resistivity or in units of siemens/meter (S/m). This parameter is a measure of the capacity of the solution to conduct electricity.
Molar conductance is the electrical conductance of a solution when it is at a specified concentration and temperature, usually 25°C. It is usually expressed in units of siemens/mole (S/mole). It is a measure of the capacity of the solution to conduct electricity when it is at a specific concentration. It can be used to predict the conductivity of the solution when the concentration changes, because the molar conductivity is independent of the concentration.
