When a lead storage battery is discharged;

When a lead storage battery is discharged;

Options

  1. ASO2\mathrm{SO}_2 is evolved
  2. Blead sulphate is consumed
  3. Clead is formed
  4. Dsulphuric acid is consumed

Correct answer

D. sulphuric acid is consumed

Step-by-step solution

H2SO4\mathrm{H}_2 \mathrm{SO}_4 is consumed during discharging of lead storage battery as, Pb changes to PbSO4\mathrm{PbSO}_4, and PbO2\mathrm{PbO}_2 changes to PbSO4\mathrm{PbSO}_4.
