Topics in Electrochemistry
1
Introduction to Electrochemistry
- Electrochemistry studies the interconversion of chemical and electrical energy
- Alessandro Volta first discovered electricity production using different metals (Zn, Cu) in 1794
- Volta's battery led to water electrolysis, proving H₂O can be split into H₂ and O₂
2
Galvanic Cells (Chemical to Electrical Energy)
- Convert chemical energy into electrical energy spontaneously
- Daniel cell is the most common example with Zn and Cu electrodes
- Consists of two half-cells connected by salt bridge
3
Reactivity Series and Applications
- Metals arranged in decreasing order of reactivity: K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Hg > Ag > Au
- More reactive metal can displace less reactive metal from its salt solution
- Metals above hydrogen can displace H₂ from dilute acids
4
Electrolytic Cells (Electrical to Chemical Energy)
- Use electrical energy to bring about non-spontaneous chemical reactions
- Consist of electrolyte and two electrodes connected to external power source
- Anode is positive electrode (oxidation), cathode is negative electrode (reduction)
