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.
