Identify the conjugate acid-base pairs in the following reactions.

Question

(a) NH4+(aq) + OH-(aq) <---> NH3(aq) + H2O(l)

Answer 1

In this reaction,
- the conjugate acid-base pair is NH4+ (acid) and NH3 (base), as NH4+ can donate a proton (H+) to become NH3.
- the other conjugate acid-base pair is H2O (acid) and OH- (base), as H2O can donate a proton (H+) to become OH-.
