1. For the proposed galvanic cells, calculate the electrode potentials of half-reactions and EMF using the Nernst equation. If the concentration of the solution is not indicated, take the potential as standard. Write the equation of the anodic and cathodic processes, the molecular equation of the current-forming reaction, indicate the direction of movement of electrons and ions in the scheme Sn/SnSO4 0.1M //Cr2(SO4)3, 0.05M/Cr
