Topics in Electrochemistry
1
Electric Conduction and Conductivity
- Two types of conduction: Metallic (electronic) and Electrolytic (ionic)
- Metallic conduction involves flow of electrons through conduction band
- Electrolytic conduction involves movement of ions in solution or molten state
2
Kohlrausch's Law and Applications
- At infinite dilution, each ion migrates independently of co-ion
- Λ⁰ = n₊λ⁰₊ + n₋λ⁰₋ (sum of ionic contributions)
- For strong electrolytes: Λ = Λ⁰ - a√c (linear relationship)
3
Electrolytic Cells and Electrolysis
- Electrolysis: breaking down ionic compounds by passing electricity
- Anode (+): oxidation occurs, cathode (-): reduction occurs
- In electrolytic cells, electrical energy converts to chemical energy
4
Galvanic Cells and Cell Potential
- Galvanic cells convert chemical energy to electrical energy
- Spontaneous redox reactions generate electricity
- Anode (-): oxidation, cathode (+): reduction
