Galvanic & Electrolytic Cell Electrode Reactions
原电池与电解池电极反应规律
Theoretical Identity Description:
Electrochemical fundamental rule: Oxidation always occurs at the Anode (负极 in galvanic, 阳极 in electrolytic), and Reduction always occurs at the Cathode (正极 in galvanic, 阴极 in electrolytic).
Rigorous Derivation Tree
Foundational identity statement defined under standard mathematical conditions.
Targeted algebraic evaluation and parameter substitution.
CSCA Exam Triggers & Traps
Use for fuel cells, lithium-ion rechargeable batteries, and chlor-alkali electrolysis equations.
Electrons flow ONLY through the external wire, NEVER through the internal electrolyte solution. Ions conduct charge inside the solution.
