Research on Electric Conductivity of Glycine Solution

The electric conductivity of glycine solution in different concentration was measured.It showed that the relation of the conductivity with conductive ions' concentraton deviates too much from formet theory.To explain the deviation,two theories were presented.They are dielectric theory and "dipole atmosphere" molde.All of them give reasonable and satisfactory interpretation on the relation of the conductivity with concentration of conductive ions and zwitterions,and shed more light on the unique zwitterion existence of amino acids.
