The solubility of anhydrous uric acid was measured in 0.30 mol dm
−3 LiCl solutions as a function of hydrogen ion concentration at 25 and 37°C. No influence of the lithium ion on the solubility
of uric acid was detected. The “litholytic” effect of lithium reported in literature can possibly be explained by the higher
solubility of lithium hydrogenurate as compared to other alkali metal hydrogenurates.
