1. Draw up a diagram of a galvanic cell from Cd (E° = - 0.40 V) and Ag (E° = 0.8 V) immersed in solutions of their own salts with an ion activity of 10 3 and 10-1 mol / l, respectively. Record the processes on the electrodes. Calculate the EMF for the indicated concentrations of solutions, as well as the value of the standard EMF.
