Abstract:The stability constants of the Ca, Sr and Ba complexes with citrate ion have been determined as a function of the temperature, in the presence of 0.2 M NH,CI. There is also evidence for 1 : 2 complexes, the constants of which are reported. The stability constants for the Sr and Ba monocomplexes show a minimum at 30'C. Above this temperature, there exists a linear relationship between the enthalpy and the entropy of complex formation, the isokinetic temperature being 104 ' C .

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
