Question

A common shorthand way to represent a voltaic cell is to list its components as follows: anode/ anode, solution ll cathode, solution/ cathode. A double vertical line represents a salt bridge or porous barrier. A single line represents a boundary between two phases, such as solid and solution. Write the half-reactions and overall cell reaction represented by Fe/Fe2+ll Ag+/ Ag and determine Eo net for the cell.

Explanation / Answer

Fe -- > Fe2+ 2e-    E1 Ag+ + e- ---> Ag   E2 multiply second equation by 2 to balance electrons: 2Ag+ + 2e- ---> 2Ag add equations: Fe + 2Ag+ ---> Fe2+ + Ag Eo = E1+E2 (these have to be from your textbook so whatevervalues you are given are what you need to plug in)
