Nadine April 15, 2023 в 05:59The conjugate acid-base pairs for the given reaction are CN^- / HCN and OH^- / H2O. In the reaction, CN^- acts as a base and accepts a proton from H2O to form its conjugate acid, HCN. Therefore, CN^- / HCN are a conjugate acid-base pair. Similarly, H2O acts as an acid and donates a proton to OH^- to form its conjugate base, OH^- . Therefore, OH^- / H2O are also a conjugate acid-base pair in this reaction.
