Calculate the standard cell potential given the standard reduction potential of the following?
Calculate the standard cell potential due to the reduction potential following rule: Al3 + + 3e -----> Al; Eo =- 1.66V Ag + + e -------> Ag, Eo = 0.799 V tarnish on silver is the Ag2O compound. A tarnished spoon silver is placed in an aluminum pan of boiling water. When enough salt is added to the solution conducts electricity, the pigmentation disappears. Imagine the two halves of this redox reaction are separated and connected by a wire and a salt bridge.
standard cell potential or emf = pot is simply rust. oxid.pot anode. oxide cathode of the pot is the inverse of the pot add red and SICE became a redox reaction at the anode is the metal (cell half) that have greater meaning boat oxide (AL), so emf = 1.66 - (-0.799) = 2.459
