چکیده
ABSTRACT. For lump and nanocobalt sulfate (CoSO4) in pure water, the affiliation thermodynamic association characteristics were measured at 298.15, 303.15, 308.15, 313.15 K. Based on bulk nano CoSO4 molar conductance, estimates made for parameters of solvation, such as activity coefficient, free energy association, enthalpy constant, entropy association. We discussed about each these solvation parameters. Two stoichiometric complexes formed by interaction CoSO4.7H2O with fuchsin acid: 1:1 1:2 In case (CoSO4.7H2O/fuchsin acid) compared to (fuchsin acid water solvent), complex Kf ∆Gf are higher, indicating simpler formation. The temperature increase resulted a drop formation constants. complexation's negative values demonstrate that process synthesis was spontaneous improved spontaneity.
