Answer to Question #249320 in General Chemistry for mhs

Question

 Calculate the electrode potential generated by the cell in the given notation:     

      Al(s)l Al3+(aq) ll I 2(s) l I – 1(aq)          When [Al+3] = 4.0 x 10 -3 M and [I – 1 ] = 0.010 M

Answer 1

The potential of the electrode E in chemistry and electrochemistry, by definition, is the electromotive force of a cell constructed from two electrodes.

E cells = E cathode – E anode
