Thermodynamic Stability Constant, Thermodynamic parameters of [MnII-antibiotics-vitamin-Bx] Systems


Polarographic technique was used to determine the thermodynamic parameters such as enthalpy change (ΔH), free energy change (ΔG) and entropy change (ΔS) of Mn(II) complexes with neomycin, chlortetracyclin, oxytetracyclin, tetracyclin, penicillin-V, and penicillin-G as primary ligands and vitamin-Bx as secondary ligand at pH = 7.30 ± 0.01 and an ionic strength µ = 1.0 M NaClO4 . The study was carried out at two different temperatures i.e. 250C and 350C to determine the thermodynamic parameters.
