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 sample was found to have a pH of 4.95.
What would be the ratio of the unprotonated form, A-, to the protonated form, HA, for uric acid in this urine sample?
