Question: Uric acid dissociates with a pKa of 5.80 and can be treated as a simple monoprotic acid in this pH range. its solubility in urine depends on the relative amount of protonated and unprotonated forms. A urine sampple was found to have a pH of 5.95. What would be the ration of the unprotonated form, A-, to the protonated form HA, for uric acid in this urine sample?
