44. Solving a chemistry problem

1. For the following system (an electrode immersed in an electrolyte solution containing an ion of the same name as the electrode material), write the equation for the electrochemical reaction that occurs on the electrode surface until equilibrium is established in the system. Calculate the potential of the metal electrode relative to the reference electrode under the following conditions.
Electrode Electrolyte volume, ml Dissolved substance and its mass Temperature, ˚С Reference electrode
