# Thermodynamic parameters of micellization and adsorption

It is known that this method is approximate because it neglects the contribution of the micelle to conductivity above the CMC therefore, leads to larger < alpha > values. The intersection point between the two straight lines gives the CMC while the ratio between the slopes of the postmicellar region to that in the premicellar region gives counter ion dissociation, α. Both critical micelle concentration from conductivity and degree of counter ion dissociation were listed in Table 1.
