Q

ionization of sulfuric acid

A
  • after the loss of the first proton, the remaining hydrogen is bound to a negatively-charged molecule.
  • electrostatic attraction between this remaining hydrogen and the negatively-charged molecule would disfavor loss the second proton, resulting in a smaller k.
