Which one of the following is the correct equation of 1st ionization of sulphuric acid?

Correct answer: B. H2SO4(aq) + H2O(l) --> H+(aq) + HSO4-

  • A. H2SO4(aq) + H2O(l) --> H+ + SO42-
  • B. H2SO4(aq) + H2O(l) --> H+(aq) + HSO4-
  • C. H2SO4(aq) + H2O(l) --> 2H+ + SO42-
  • D. H2SO4(aq) + H2O(l) --> H3O+ + SO42-

Explanation

The 1st ionisation equation involves dissociation of 1 H+ ion from H2SO4, followed by second H+ dissociation in the second ionisation.
