1. OH ^- and H ₂ F ^+ , respectively 2. H ₃ O ^+ and F ^- , respectively 3. OH ^- and F ^- , respectively 4. H ₃ O ^+ and H ₂ F ^+ , respectively

Answer: 3. OH ^- and F ^- , respectively A conjugate base is formed when the acid loses H^+ . H₂O → OH^- + H^+ and HF → F^- + H^+ . So the conjugate bases are OH^- and F^- , option (3). H₃O^+ and H₂F^+ are conjugate acids.

Answer: 3. OH\(^-\) and F\(^-\), respectively

A conjugate base is formed when the acid loses \(\mathrm{H^+}\).

\(\mathrm{H_2O \to OH^- + H^+}\) and \(\mathrm{HF \to F^- + H^+}\). So the conjugate bases are \(\mathrm{OH^-}\) and \(\mathrm{F^-}\), option (3). \(\mathrm{H_3O^+}\) and \(\mathrm{H_2F^+}\) are conjugate acids.
