| Abstract: | The first step and second step deprotonation constants of purine and uric acid in water have been determined from emf measurements of cells comprising H2 and Ag-AgI electrodes at five equidistant temperatures ranging from 15°-35°C. The pK values are fitted in the temperature equation pK = AT- 1 + B + CT by least squares method and the related standard free energies (DG°), entropies (DS°) and enthalpies (DH°) of the deprotonation processes in water have also been evaluated using the values of the coefficients A, B and C of the respective acids. |
