Abstract
The interaction of bismuth (III) citrate BiC6H5O7 with the aqueous solutions of potassium hydroxide in different concentrations was studied by means of X-ray phase analysis, IR spectroscopy, thermogravimetry and chemical analysis. The conditions for the formation of the potassium salt of bismuth (III) citrate having the composition KBiC6H4O7 · H2O were determined. Reasonability of obtaining this compound through the interaction of the aqueous solution of potassium hydroxide with bismuth (III) citrate with their molar and mass ratio equal to 1.0 was shown.
