The reduction potential at cathode is 0.5 V while the oxidation potential at anode is 0.9 V. What is the cell potential?
Question
What is the cell potential?
The reduction potential at cathode is 0.5 V
while the oxidation potential at anode is 0.9 V.
What is the cell potential?
Solution
The cell potential, also known as the electromotive force (emf), is the difference between the reduction potential at the cathode and the oxidation potential at the anode. It is calculated using the formula:
Ecell = Ecathode - Eanode
Given that the reduction potential at the cathode (Ecathode) is 0.5 V and the oxidation potential at the anode (Eanode) is 0.9 V, we can substitute these values into the formula:
Ecell = 0.5 V - 0.9 V
Therefore, the cell potential (Ecell) is -0.4 V.
