Conductance is the expression of the ease of the passing of the electrons. Specific conductance is given for most analyses and was determined by means of a conductance bridge and using a standard potassium chloride solution as a reference. Conductivity is a numerical expression of the tendency of an aqueous solution to carry an electric current.
An expression of how easily an ion flows across a membrane either through active pumps located in the membrane of ion channels; when specific ion channels open, conductance (g) for that ion increases. Electricity is conducted through an electrolytic solution due to the movement of ions. In general, the greater the number of ions in the solution higher is the conductance.
The conductivity of electrolytic solutions is governed by the following factors.
- Interionic attraction
- Solvation of ions
- The viscosity of the solvent
