Abstract	The solubility of cucurbit[6]uril in aqueous and in different solutions of alkali and alkaline earth salts has been measured. Due to the complex formation the solubility of the ligand increases. From this increase the stability constants of the cations are calculated. The solubility of cucurbit[6]uril in salt solutions after extrapolation to zero salt concentrations differs from salt to salt. These values of the solubility are different from the direct measured value of the solubility. The measured values of the stability constants with different salts are in accordance with most of the values reported. However, the presented method for the calculation of stability constants fails if the values of the stability constants exceed a certain value. This limiting value depends on the solubility of the ligand examined.
