Gout is a painful inflammation of the joints caused by an excess of uric acid in the blood and its precipitation as sodium urate (the sodium salt of uric acid), NaC5H3N4O3, in tissues of the joints. The solubility of sodium urate in aqueous solution is 7.0 mg per 100 mL at body temperature, 37°C. The normal level of sodium ion in blood plasma is 3.2 g per liter. What would be the concentration of urate ion in blood plasma if it were saturated with sodium urate?
