Problem
Based on Brønsted-Lowry theory, which of the following are acid-base reactions
Choose all answers that apply:
a. NH3 + NH3 ⇌ NH4+ + NH2−
b. Zn(s) + 2HCl(aq) → H 2(g) + ZnCl2(aq)
c. 2Cr(s) + 3Cl 2(g) → 2CrCl3(s)
d. LiOH(aq) + HBr(aq) → H2O(l) + LiBr(aq)
Solution
We are asked to identify the acid-base reactions based on the Brønsted-Lowry definition.
According to Brønsted and Lowry, an acid was classified as a proton donor while a base was a proton acceptor.
Bronsted-Lowry acid → proton (H+) donor
Bronsted-Lowry base → proton (H+) acceptor
So we look at each reaction and identify if there is a proton that has been transferred.
