The Nernst equation can be used to calculate the potential of an electrochemical cell when not under standard conditions. It is also very useful to show how ion concentration affects cell potential and the cell potential is 0.09314 V.

At 298 K, the Nernst equation simplifies to - 0.0592 v protocol Q where Q is the reaction quotient and n is the coefficient of electrons transferred if the redox equations are balanced.

In this cell copper is reduced at the cathode and oxidized.

  • 0.00V. However, the anode C.
  • When 2 +] = 0.0032 M.
  • including cathode [C. When 2 +] = 4.48 M. , so the cell potential is not 0.00 V. The cell potential can be solved using the Nernst equation. where n = 2 and Q = 0.0032/ 4.48.= 0.0592.
  • E= 0-0.0592/ 2 log (0.000174)
  • E= 0-0.0592/ 2 -3.14
  • E= 0-0.0592/ 2
  • E = 0.09314 V.
