What is an electrochemical series? How is the standard electrode potential of zinc electrode determined? Calculate the emf of the following cell at 25°C. Fe|Fe2+ (0.1 M) || Cu2+ (0.2 M) | Cu Given, E°Fe2+/Fe = -0.44 V, E°Cu2+/Cu = +0.34 V
What is electrochemical series? Write its applications. Calculate the emf of the cell: Ni/Ni2+(1M) // Pb2+ (1M) / Pb at 25°C. Write down its cell reaction. Standard electrode potential of Ni and Pb are -0.24V and -0.13V respectively at 25°C.
What is Daniel cell? How do you measure standard reduction potential of silver electrode? Calculate the emf of the following cell at standard condition, Ni/Ni2+ (0.5M) // Ag+ (0.4M) / Ag. Given E°Ni/Ni2+ =+0.25V, E°Ag/Ag+=-0.80V.
