Electrochemistry — Class 12 ISC Chemistry revision notes
A 5-page visual revision sheet for Electrochemistry, written for Class 12 ISC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Electrochemistry sheet covers
- The two kinds of cell, and the one rule that never changes
- Cell notation, written the way it is marked
- The standard hydrogen electrode, and the series it defines
- The Nernst equation and what hangs off it
- for a general cell
- at equilibrium
- free energy
- the Faraday constant
- for a single electrode
- Reading the Nernst equation without slips
- The three signs, kept in step (standard conditions)
- Conductance, and why it needs its own vocabulary
- Strong against weak, seen in the conductivity
- The conductance formulas
- conductivity
- molar conductivity
- Kohlrausch
- degree of dissociation
- dissociation constant
- faraday's laws
- Electrolysis, and the products you actually get
- Batteries and corrosion
- Overvoltage, the reason the predictions sometimes fail
- The numbers and standard potentials worth carrying in
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Electrochemistry the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
