Key Topics to Revise

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)
