b) All Arrhenius bases are also Brønsted-Lowry bases.

c) All Brønsted-Lowry bases are also Arrhenius bases.

d) The chemical formula of the conjugate acid of a Brønsted-Lowry base has one more proton than the Brønsted-Lowry base.

e) A Brønsted-Lowry acid is a proton acceptor.

Homework Answers

Answer #1
  • A Brønsted-Lowry acid is any species that is capable of donating a proton -H+

  • A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the -H+

  • An Arrhenius acid is any species that increases the concentration of  -H+ in aqueous solution

  • An Arrhenius base is any species that increases the concentration of OH- in aqueous solution

  • From the definition we can see that

  • All Arrhenius acids and bases are also Bronsted-Lowry acids and bases, but the opposite isn't true.

  • option B,Cand D are correct
