1. In an electroless deposition of Cu²+ using Fe in acidic medium, the mechanism is shown below: Cu²+ +2e=Cuº (Ed=0.34 V SHE) and Fe=Fe²+ + 2e- (E°= -0.41 V SHE). identify the oxidation and reduction reactions (i) (ii) (iii) Can H₂ gas be used instead of Fe? Why? Can O₂ gas used instead of Fe (E = 1.23 V SHE)? Why? (iv) Identify the direction of electrons flow and current flow. B. Can we get work from the above cell? If yes, how? If no, why?
