Abstract: Based on the model presented in part I of this work, the inner capacity depen-dence on surface charge was estimated for Hg/aqueous solution interface at five different temperatures.The results show that the treatment used in our previous paper is suitable to aqueous systems. However, at the vicinity of freezing point (273 K) for aqueous solutions, the formation of ice-like structure due to the adsorbed water molecules associated with H-bond at the inner-layer may be occured, and local-order array will tend to random distribution as soon as the temperature being higher.
