Exam focus
How Electrochemistry is asked
Numerically dense and therefore predictable: most questions come from the Nernst equation, cell EMF, or Faraday's laws, and all three are procedural once the setup is right. The recurring difficulty is not the mathematics but keeping oxidation, reduction, anode and cathode straight in a cell you have just been handed.
Cheat sheet
Electrochemistry formulas worth memorising
| Quantity | Formula |
|---|---|
| Cell potential | E°(cell) = E°(cathode) − E°(anode) |
| Nernst equation (298 K) | E = E° − (0.059/n) log Q |
| Free energy and EMF | ΔG = −nFE, F = 96500 C/mol |
| EMF and equilibrium | E° = (0.059/n) log K at 298 K |
| Faraday's first law | m = ZIt |
| Molar conductivity | Λm = κ × 1000 / molarity |
| Kohlrausch's law | Λm° = λ°(cation) + λ°(anion) |

Common mistakes in Electrochemistry
- Mixing up anode and cathode between cell types. Oxidation is always at the anode and reduction always at the cathode, but the anode is negative in a galvanic cell and positive in an electrolytic one.
- Using 0.059/n at a temperature other than 298 K. That coefficient already has 298 K substituted into 2.303RT/F, so any other temperature requires the full expression.
- Writing the reaction quotient upside down in the Nernst equation. Q is products over reactants for the cell reaction as written, and inverting it flips the sign of the correction term.
- Confusing conductivity with molar conductivity. Conductivity falls on dilution because there are fewer ions per unit volume; molar conductivity rises because the ions that remain dissociate more completely.
- Forgetting to account for the number of electrons in Faraday's law calculations. Depositing one mole of Al³⁺ requires three faradays, not one.

JEE Electrochemistry Quiz - FAQs
Why is the standard hydrogen electrode assigned a potential of zero?
Because only potential differences are measurable, never absolute electrode potentials. The SHE is a defined reference point set at 0.00 V by convention, and every other standard electrode potential is quoted relative to it.
What does a positive cell potential tell you?
That the cell reaction as written is spontaneous, since ΔG = −nFE makes ΔG negative when E is positive. A negative E means the reverse reaction is the spontaneous one, and that driving the written reaction requires an external supply.
