Abstract The present study dealt with the different physical parameters for some electrolytes and their complexes in different solutions like association constant, formation constants, solubilites and refractive indices measurements. The obtained results can be summarized as follow: 1- The association thermodynamic parameters KA and ΔGA are greater on using nano AgNO3 than bulk AgNO3 in mixed (MeOH-H2O) solvents at all temperatures used. 2-The complex formation constants Kf and ΔGf for bulk and nano AgNO3 with acetylacetone are greater for 1:2 complexes than 1:1complexes favouring more probability to happen. 3- All the complex formation parameters for interaction of both AgNO3 forms with acetyl acetone are greater in using bulk AgNO3 than nano AgNO3 at all the four different temperatures used. 4- The association thermodynamics for the solvation of bulk and nano AgNO3 are greater in case of 10% EtOH-H2O than that of water. 5- Both 1:2 and 1:1 complexes gave smaller complex formation parameters for bulk and nano AgNO3 with acetyl acetone in 10% EtOH-H2O in pure water. 6- The solubility products PKsp for saturated both bulk and nano Ag2CrO4 increased by increasing mole fraction of acetonitrile in mixed AN-OH solvents and with rise of temperature favouring more solvation. 7- The free energies of solvation for saturated bulk and nano Ag3PO4 solutions, and increased in positivity with increase of the percentage of(An) in mixed AN-OH solvents and with rise of temperature favouring less solvation. 8- All the polarization parameter for bulk Ag2CrO4, nano Ag2CrO4, bulk Ag3PO4, nano Ag3PO4 are increased by increase of temperature indicating more polarization parameters. |
