thermodynamics of ion pairs in mixed solvents i the standard Association Constant of the ion pair mgso4 oin 0 03226 co nh2 2 0 96774 h2o
The Journal of Chemical Thermodynamics, 2001Co-Authors: Jiazhen Yang, Rubo Zhang, Hong Liu, Jie WangAbstract:Abstract The standard potential of the (Ag, AgCl) electrode E o , the standard second ionization Constant of sulfuric acid K 2 , and the standard Association Constant of the ion pair [MgSO 4 ] o , K in {0.03226 CO(NH 2 ) 2 + 0.96774 H 2 O } at five temperatures from 278.15 K to 318.15 K were determined from precise e.m.f. measurements of different cells without liquid junction. The dependence of p K on temperature T is expressed by the empirical equation p K = 6.617 − 777.9 · ( K / T ) − 0.02001 · ( T / K ). The other thermodynamic functions of the Association process were also calculated and show that the driving force for the process is the entropy of Association.

thermodynamics of ionic Association 1 the standard Association Constant of the ion pair li b oh 4
Thermochimica Acta, 2000Co-Authors: Jiazhen Yang, Bai Sun, Pengsheng SongAbstract:Abstract Values of emf for the cell without liquid junction Pt, H 2 (101.325 kPa) |Li 2 B 4 O 7 ( m 1 ), LiCl ( m 2 )|AgCl–Ag are reported at five temperatures from 278.15 to 318.15 K. The standard Association Constant of ionic pair Li + B(OH) 4 − , K a , is determined by a fitting with the cell results. The dependence of p K a on temperature T is expressed in empirical equation: p K a =−131.6 K / T −0.08996−1.856×10 −3 T / K . The other thermodynamic quantities of the Association process are calculated and show that there truly exists ion pair Li + B(OH) 4 − and the driving force for the ion Association reaction is Association entropy.

The Journal of Chemical Thermodynamics, 1997Co-Authors: Jiazhen Yang, Pengsheng Song, Dongbao WangAbstract:Abstract Values of e.m.f. for the cell without liquid junction: Pt H 2 ( p = 101.325kPa)|K 2 B 4 0 7 ( m 1 ) LiCl( m 2 )|AgCl Ag are reported at seven Constant ionic strengths from 0.07 to 2.0 mol·kg −1 at five temperatures from 278.15 K to 318.15 K. The standard Association Constant K a of the ionic pair Li + B(OH) 4 − , is determined by a fit with the cell results. The dependence of p K a on temperature T is expressed by the empirical equation: p K a = −149.8(K/ T ) + 0.09024 − 2.112·10 −3 ( T /K). The other thermodynamic quantities of the Association process were also calculated and show that the driving force for the ion Association reaction is the Association entropy.

determination of Association Constant of host guest supramolecular complex molecular recognition of carbamazepine antiseizure drug with calix 4 arene
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015Co-Authors: C Meenakshi, P Jayabal, V RamakrishnanAbstract:Abstract The thermodynamic property of the host–guest, inclusion complex formed between p - t -butyl calix(4)arene which is a supramolecule, and the antiseizure drug, carbamazepine was studied. p - t -Butyl calix(4)arene has been used as a host molecule and carbamazepine as a guest molecule. Optical absorption spectral studies were carried out to investigate the molecular recognition properties of p - t -butyl calix(4)arene with carbamazepine. The stochiometry of the host–guest complexes formed and the Association Constant were determined. An interesting 1:2 stochiometric host–guest complex was formed. Job’s continuous method of variation and Benesi–Hildebrand expression were used for the determination of binding Constant and the stochiometry of the host–guest complex formed. Molecular dimension of the host molecule plays a vital role in the formation of the host–guest stochiometric complexes.
