1. In an electroless deposition of Cu+ using Fe in acidic medium, the mechanism is shown below: Cu+ +2e=Cu (Ed=0.34 V SHE) and Fe=Fe+ + 2e- (E= -0.41 V SHE). identify the oxidation and reduction reactions (i) (ii) (iii) Can H gas be used instead of Fe? Why? Can O 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?
