77. Solving a chemistry problem

9. The galvanic cell consists of two hydrogen electrodes in solutions with the pH values given in the table. Calculate the electromotive force of this element at 25°C if the hydrogen partial pressures in both electrodes are equal to 1.

Task: pH,1=5.9, pH,2=1.2

When solving this task, pay attention to the fact that this system is a kind of concentration galvanic cells. The answer should indicate the polarity of the electrodes in the presented galvanic cell.
