Sodium urate (C5H3N4O3Na)
Solubility of sodium urate is 8.5 g/L.
Mols sodium urate = 8.5/190 = 0.0447 and with the volume of 1L this is a 0.0447 M solution.
So you have a 0.15 M Na^+ and the minimum C5H3N4O3Na is 0.0447 which means the minimum (Na^+) must be 0.0447 M.
Gout is an extremely painful disease caused by an error of nucleic acid metabolism or excretion that leads to a buildup of uric acid in body fluids, which is deposited as a
slightly soluble sodium urate (CsH3N403Na) in the soft tissues of joints. If the extracellular Na+ in humans is 0.15 M and the solubility of sodium urate in water is 0.085 g/100 ml, what is the minimum urate ion concentration (UR-) that will cause a
deposit of sodium urate?
