(2)Classification of cell.

(3)The circuit diagram of dry cell and lid acid cell.

slide3
Lesson decleared
  • The charging discharging equation of lid acid cell.Internal diagram of lid acid cell.
slide5
The charging and discharging equation of lid acid cell.
  • H2SO4  →  H+ + HSO4−
  • Pb− →  PbSO4+H+2e−+HSO4
  • PbO2+3H+HSO4−+ →PbSO4+2H2O
  • Pb+2H2SO4+PbO2 →2H2SO4+2H2O
slide6
