Verified step by step guidance1
Recall that a Brønsted–Lowry acid is a species that donates a proton (H\textsuperscript{+}), and a Brønsted–Lowry base is a species that accepts a proton.
Identify the two species in each pair and determine if one can lose a proton to form the other, or if one can gain a proton to form the other.
For example, consider the pair \( \mathrm{N_2H_5^+} \) and \( \mathrm{N_2H_4} \): check if \( \mathrm{N_2H_5^+} \) can donate a proton to become \( \mathrm{N_2H_4} \), which would make them a conjugate acid-base pair.
Verify that the difference between the two species is exactly one proton (H\textsuperscript{+}), confirming the conjugate acid-base relationship.
Apply this reasoning to each pair to identify which pair fits the Brønsted–Lowry conjugate acid-base definition.
