Question

With the help of standard reduction potential in electrochemical series answer the following

questions regarding the Galvanic cell:

Fe|1.0 M FeCl3||1.0 M MgCl2|Mg

(a) Identify the cathode and anode
(b)calculate the cell voltage.
​

Answer 1

Answer:

The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is needed because oxidation is the reverse of reduction.
