Electrochemistry — Class 12 Maharashtra HSC Chemistry revision notes
A 6-page visual revision sheet for Electrochemistry, written for Class 12 Maharashtra HSC 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
- Galvanic (voltaic) cell
- Electrolytic cell
- Electrode potential
- Electrolytic vs Galvanic Cells
- Electrolytic
- Galvanic
- Conductance of Solutions
- Kohlrausch's Law of Independent Migration
- at infinite dilution, each ion contributes independently of its co-ion
- degree of dissociation of a weak electrolyte at concentration c
- dissociation constant from Ostwald's dilution law
- Measuring Conductivity: the Wheatstone Bridge Method
- Electrolysis: Which Half-Reaction Actually Wins
- mass deposited or liberated at an electrode
- Quantitative Electrolysis
- charge passed
- moles of electrons passed, 1 Faraday = 96500 C
- mass of product, mole ratio from the half-reaction stoichiometry
- two cells in series, same charge passed through both
- Galvanic Cell Notation
- Standard Cell Potential and the Nernst Equation
- standard cell potential, IUPAC convention (every E° is a REDUCTION potential)
- Nernst equation, general reaction aA+bBto cC+dD
- Thermodynamics of the Galvanic Cell
- electrical work equals the DECREASE in Gibbs energy
- at standard state
- link to the equilibrium constant, combining with Δ G°=-RTln K
- Reference Electrodes
- Galvanic Cells in Everyday Use
- Dry (Leclanche) cell
- Lead storage battery
- Ni-Cd (NICAD) cell
- Mercury cell
- H2-O2 fuel cell
- Fuel Cells: Advantages and Drawbacks
- Electrochemical Series: Reading the Table
- Symbols
- 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.
