Hydrolysis of 1 mol of peroxodisulphuric acid produces:

Hydrolysis of 1 mol of peroxodisulphuric acid produces:

  • A. 2 mol of sulphuric acid.
  • B. 2 mol of peroxomono sulphuric acid.
  • C. 1 mol of sulphuric acid and 1 mol of peroxomono sulphuric acid.
  • D. 1 mol of sulphuric acid, 1 mol of peroxomono sulphuric acid, and 1 mol of hydrogen peroxide.

Step-by-step solution

Peroxodisulphuric acid (H2S2O8) hydrolyzes by breaking the peroxide bond, producing one mole each of sulphuric acid (H2SO4) and peroxomonosulphuric acid (H2SO5). Further hydrolysis of H2SO5 would yield H2O2, but the primary reaction gives only H2SO4 and H2SO5.
