Explanation

According to the Brönsted-Lowry theory, a conjugate acid-base pair differs only by one proton. A conjugate acid has one extra proton compared to its corresponding base. Therefore, by adding one proton (H+H^+) to each of the given Brönsted bases, we obtain their respective conjugate acids.

Solution Steps

  1. Step 1: For the base NH2−NH_2^-, adding one proton (H+H^+) gives the conjugate acid NH3NH_3.

  2. Step 2: For the base NH3NH_3, adding one proton (H+H^+) gives the conjugate acid NH4+NH_4^+.

  3. Step 3: For the base HCOO−HCOO^-, adding one proton (H+H^+) gives the conjugate acid HCOOHHCOOH.
