We are asked which statement is false about the following acid-base reactions.
Let’s define a Bronsted-Lowry Acid and a Bronsted-Lowry Base.
Bronsted-Lowry acid → proton (H+) donor
Bronsted-Lowry base → proton (H+) acceptor
Based on the Lewis definition:
Lewis acid is an electron pair acceptor.
Lewis base is an electron pair donor.
Which statement is false?
a) H+(aq) + H2O(l) → H3O+(aq) is a Lewis acid-base reaction
b) BF3 + F– → BF4– is a Lewis acid-base reaction
c) Ni2+(aq) + 6H2O(l) → [Ni(H2O)6]2+(aq) is a Lewis acid-base reaction
d) Ni2+(aq) + CO32–(aq) → NiCO3(s) is a Lewis acid-base reaction
e) all Brønsted-Lowry bases are also potential Lewis bases
f) HNO2 is a Brønsted-Lowry acid but is not a Lewis acid
