Question

An electrochemical cell is constructed using electrodes with the following half-cell reactions

Answer 1

In oxidation reduction for copper and alluminium is generally represented as follows
Al/Al ions/cu ions/cu
Al ->Al ions plus 2e-
cu ions plus 2e- ->cu(s
Al plus cu ions ->Al ions plus cu(s)
overall cell potential is therefore
1.66v plus 0.34v which is equal to 2.00v

Answer 2

Option (c) is the correct answer.

The given equations have been attached the picture:

As we know,


= + 0.34V - (- 1.66V)
= 0.34V + 1.66V
= +2.00V
Answer: + 2.00V
