Uric acid dissociates as exposed in the figure at the right, Ask an Expert

Academics

Uric acid dissociates as exposed in the figure at the right with a pKa of 5.80, as well as 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 5.34. Define what would be the ratio of the unprotonated form A- to the protonated form, HA, for uric acid in this urine sample?
