Abstract

During tshe examination of the final state of the reaction on the electrochemical kinetics, it has become essential to study the duration needed for the B-lead dioxide to attain equilibrium potential in nitrate solution. This was studied by first depositing B-lead dioxide on platinum foil from 1M lead nitrate solution using a H-type cell and introducing freshly prepared anodes (for each experiment) in the experimental cell containing deaerated lead nitrate solution. The potential measurements were carried out against saturated calomel electrode (SCE) and at a temperature of 303 + 0.2 K for 60 minutes. The variation of equilibrium potential with time was studied for (i) B lead dioxide prepared for different durations (ii) different concentrations of lead nitrate and (iii) different nitric acid concentrations. The buffering action was also seen by taking lead acetate in acetic acid. In general, the equilibrium potential for B- Pb02 is quickly attained in acidic solutions. It is known that lead dioxide behaves as a nonstoichiometric oxide electrode and the variations in the deviations from the ideal stoichiometry. The variation of equilibrium potential with time is discussed taking into consideration of these facts
