Abstract : The entropy of mixing of binary metallic solutions was studied. The contribution to the entropy of mixing arising from the change in the statistical distribution of electrons was the primary interest when two metallic components were mixed. The general nature of the deviations of the measured entropy of the mixing from the ideal behavior is recognizable from the nature of the assumptions involved in reducing the complete statistical formulation to the simple form of equation, which is based on the assumption of a completely random distribution of the two components of the solution. For metals, theoretical treatments indicate that the electronic heat capacity is linearly dependent on the absolute temperature. Consequently, integration to the temperature of measurement of the thermodynamic entropy is possible and can lead to the contribution of the electrons to the entropy of mixing. (Author)
