| Abstract This work includes a conductivity study of Barbituric acid (BA) in water at temperatures (288.16-318.16).The data were analyzed by applying Lee-Wheaton equation for symmetrical electrolyte. It is found that the equivalent conductivity at infinite dilution (Λo) and the ion association constants KA increase with increasing temperature. The distance parameter between ions (R) indicates the formation of solvent separated ion pairs. The association of (BA)and its complexes with alkaline-earth metals Mg,Ca and Ba as chlorides have been carried out at temperatures (288.16-318.16oK).Analysis of the results indicate that the ionic conductivity λo M2+ increase with increasing temperature with the formation of ion-pair (MX)+.The ( R ) values for the three complexes found to be ( 7.0-9.0Ao ) . The Walden –product (Λo µ) is also determined and discussed. | ||
