| Abstract | ||
| The electrical conductance and thermodynamic properties data for nano (NH4)2Fe(SO4)2, FAS fluids like molar conductance, association constant and degree of dissociation of different concentrations of nano ferrous ammonium sulfate fluids,FAS in H2O were measured at three different temperatures. Also from the values of the measured molar conductance, the limiting molar conductance, Gibbs free energies, enthalpy and entropies were calculated and discussed. The aim of the work is to estimate the different thermodynamic parameters depend on the molar conductance for nano fluid (NH4)2Fe(SO4)2,FAS material. The method used is measuring molar conductance by using A JENCO, Vision plus EC3175 (USA) conductance meter and temperature meter with an electrode of cell constant equal (1) connecting with ultra-thermostat of the type Kottermann 4130. The measuring electrical conductance and thermodynamic properties are necessary for manufacturing industries especially in those using electrical and thermo chemical devices. | ||
