In the framework of the research carried out on the behaviour of the salts of bile acids in aqueous solutions, the lead (11) cholate solubility was determined at 25degreesC and in 0:100, 0.500 and 0.800 mol dm(-3) N(CH3)(4)C1, as ionic medium. The change of its solubility was studied as a function of the cholate and hydrogen ion concentration. Solubility and electromotive force measurements of suitable galvanic cells were carried out and from the results lead (11) cholate solubility product could be calculated and the presence of associated species in solution in the ratio 1:3 and 1:4 between. lead (11) and cholate was assumed. The relative constants were determined, as well. The results of this work allow us to obtain the free cholate concentration in equilibrium with solid lead (11) cholate.
