“…Many studies on thermodynamics and dissociation constant have been conducted in connection with conductometry with the use of many equations [1][2][3][4][5][6]. Friedrich Kohlrausch (1840-1910), a German chemist, initially proposed the Kohlrausch equation as the outcome of extensive experimental effort.…”

The dissociation constant is a quantitative measure of the strength of an acid in solution. This study examines dissociation constant for the series substituted acids like Ortho-alkoxy-4-formylbenzoic acid. The use of (2-methoxy ethanol) as a solvent contributed to the study expected to form free ions or solvent separated ion pair which has been studied with the use conductometric method at different temperatures ranged from 293.15 to 318.15K. The study aims at figuring out dissociation constant, equivalent conductance at infinity dilution, and Walden product by minimization technique using Fuoss-Hsia for both (Modified and Complete) equations. It has been found in the results that the calculated values based on statistical sum square (different between practical and theoretical values) is equivalent conductance at infinity dilution and dissociation constant. It has also been observed that increase the temperature leads to the increase of the molar conductance at infinity dilution, and the increase in association. Moreover, the substituted alkoxy group also affected dissociation of compounds. In this study, the thermodynamic parameters (Ho, Go and So) have also been evaluated and discussed. Finally, the effect of substituent groups on rate of dissociation was studied and explained with agreement to the principles of mesomeric(M) and Inductive effect(I) of substituent groups on dissociation constant.

“…[12][13][14] These findings prompted us to investigate similar anodic substitutions of other chalcogeno compounds, tellurides. In contrast to the electrochemical study of organosulfur and selenium compounds, the anodic behavior of organotellurium compounds has been less studied [15][16][17][18][19][20][21] except for tellurophene. 22 In this work, we studied on anodic oxidation of various tellurides, PhTeR (R = CF 3 CH 2 , CF 2 H, Me, Ph) in methanol containing various supporting electrolytes (YO − M + ) such as p-tosylate, benzenesulfonate, acetate, and benzoate salts and we found the efficient formation of the corresponding hypervalent tellurium compounds having Te-O bonds.…”
