Under the Bronsted-Lowry model, what does a base do during a reaction?
AIt donates protons
BIt accepts electrons
CIt donates electrons
DIt accepts protons
Answer & Solution
Correct answer: D. It accepts protons
1. A hydrogen atom that has lost its electron is a bare proton.
2. The Bronsted-Lowry model sorts substances by what they do with that proton.
3. An acid gives a proton away, so it is a proton donor.
4. A base takes a proton, so it is a proton acceptor.
