Abstract EN
In the first part of this work we have measured the electrical conductivity of 4-amino salicylic acid (4-ASA) solution in water, methanol and ethanol at different temperatures (293.16-313.16 K).
The experimental results were analyzed using Lee-Wheaton equation (LW) for symmetrical electrolytes (1:1).
The conductivity parameters were calculated: the equivalent conductivity at infinite dilution (Λo), the association constant (KA) and the mean distance values between ions (R) at the best standard deviation σs(Λ).
It is found that by increasing the temperature, the values of Λo increased, in contrast of that the values of KA decreased in ethanol only, R are found to be between (2-29 )Ao which indicates the formation of solvent separated ion pairs in solution.
By Vant Hoff equation we have calculated the thermodynamic parameters (ΔG, ΔH and ΔS) of ion association in solution.
The second part of this work is the measurement of electrical conductivity of (4-ASA) in water with chlorides of each of nickel, cobalt and manganese at different temperatures (293.16-313.16 K) and calculation of conductivity parameters by Lee-Wheaton equation for unsymmetrical electrolytes (2:1), besides the thermodynamic parameters were also performed.
The Walden-product (Λoη) was also determined and discussed.
