9. Which of the following statements is true?
Choose all that apply.
a) A Brønsted-Lowry base is a proton donor.
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.
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
