The pH of a 0.33 M solution of barbituric acid (HC,H;N,0;) is measured to be 2.25.Calculate the acid dissociation constant K, of barbituric acid. Be sure your answer has the correct number of significant digits.

Since pH = -log[H+] where [H+] = concentration of H+ ions Hence 2.25 = -log[H+] => [H+] = 5.62 X…
