Convert each of the potentials. The silver–silver chloride and calomel reference electrodes are saturated with KCl, KCl, resulting in cell potentials of +0.197 V and +0.241 V with respect to the standard hydrogen electrode (S. H.E.), respectively. If an electrode has a potential of 0.9120.912 V with respect to a standard hydrogen electrode (S. H.E.), what is the potential with respect to a silver–silver chloride electrode?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The correct answer is "hydrogen".
