Identify the Lewis acid and Lewis base in each reaction:Fe³⁺ + 2H₂O ⇄ FeOH²⁺ + H₃O⁺
yan [13]

In the given reaction Fe³⁺ + 2H₂O ⇄ FeOH²⁺ + H₃O⁺ Lewis acid is Fe³⁺ and the Lewis base is H₂O.

<h3>What is a Lewis acid and Lewis base?</h3>
  • According to the Lewis theory of acid-base reactions, acids accept pairs of electrons and bases donate pairs of electrons.
  • Any substance like H+ ion, which is capable of accepting a pair of nonbonding electrons or an electron-pair acceptor is known as a Lewis acid.
  • Any substance, like the OH- ion, that is capable of donating a pair of nonbonding electrons or an electron-pair donor is a Lewis base.
  • From the Lewis theory, with no change in the oxidation numbers of any atoms, acids react with bases to share a pair of electrons.
