AIt donates a proton to another compound
BIt accepts a proton from another compound
CIt donates an electron pair to a base
DIt accepts an electron pair from a base
Answer & Solution
Correct answer: A. It donates a proton to another compound
1. The Bronsted-Lowry model is built around the proton, the hydrogen ion.
2. Whichever compound hands that proton over is the acid.
3. Whichever compound takes it up is the base.
4. Donating or accepting an electron pair is the Lewis model, a later and more general one.
