Verified step by step guidance

Identify the Bronsted-Lowry acid and base in the reaction. A Bronsted-Lowry acid donates a proton (H+), while a base accepts a proton.

Examine the given reaction: HC2O4^- (aq) + H2O (l) ⇌ H3O^+ (aq) + C2O4^2- (aq). Here, HC2O4^- donates a proton to H2O, forming H3O^+ and C2O4^2-.

Determine the conjugate pairs. A conjugate acid-base pair consists of two species that differ by a single proton.

Identify HC2O4^- and C2O4^2- as a conjugate acid-base pair. HC2O4^- is the acid (proton donor), and C2O4^2- is its conjugate base (proton acceptor).

Verify that the other options do not form conjugate acid-base pairs. H2O and C2O4^2- do not differ by a proton, and HC2O4^- and H3O^+ are not related by a single proton transfer.
