When a lead storage battery is discharged;

Options

  1. ASO 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

H ₂ SO ₄ is consumed during discharging of lead storage battery as, Pb changes to PbSO ₄ , and PbO ₂ changes to PbSO ₄ .
