Abstract The thesis consists of three chapters besides arabic summary and english summary. Chapter one is about general introduction to the thermodynamic parameters , conductivity , nano particles and literature survey about thermodynamics of solvation for some materials of the thesis. Chapter two is the experimental part , explains the chemicals used , apparatus , techniques , preparation of solutions , preparation of nano zinc sulphate , identification of nano salt density , solubility and conductivity measurements. Chapter three is the results and discussion . It divides into three parts. Part one is about the estimation of thermodynamic parameters for the solvation of nano ZnSO4 and bulk ZnSO4 in presence and absence of calcon carboxylic acid in pure water and mixed methanol – water solvents at different temperatures. Part two deals with the conductivity data necessary for the association and complexation of copper sulphate without and with calcon carboxylic acid in pure water and mixed methanol (MeOH) – water solvents at different temperatures (298.15, 303.15, 308.15, 313.15K). Part three is about the solubility data for CuSO4 , nano ZnSO4 , and bulk ZnSO4 in n- propanol – water mixtures at different temperatures. Key words: thermodynamic parameters- bulk zinc sulphata- copper sulphate- nano zinc sulphate- mixed methanol water- mixed propanol water- calcon carboxylic acid- molar volume- Van der Waals volume- electrostriction volume. |
