A buffer solution made from acetic acid \( \left(\mathrm{HCH}_{3} \mathrm{CO}_{2}\right) \) and sodium acetate \( \left(\mathrm{NaCH}_{3} \mathrm{CO}_{2}\right) \) was titrated with hydrochloric acid. What is the net ionic equation for the reaction? \[ \begin{array}{l} \mathrm{HCl}(a q)+\mathrm{OH}^{-}(a q)=>\mathrm{H}_{2} \mathrm{O}(l)+\mathrm{Cl}^{-}(a q) \\ \mathrm{H}_{3} \mathrm{O}^{+}(a q)+\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)=>\mathrm{H}_{2} \mathrm{O}(l)+\mathrm{H}_{2} \mathrm{CH}_{3} \mathrm{CO}_{2}(a q) \\ \mathrm{H}_{3} \mathrm{O}^{+}(a q)+\mathrm{CH}_{3} \mathrm{CO}_{2}^{-}(a q)=>\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(l) \\ \mathrm{H}_{3} \mathrm{O}^{+}(a q)+\mathrm{OH}^{-}(a q)=>2 \mathrm{H}_{2} \mathrm{O}(l) \\ \mathrm{HCl}(a q)+\mathrm{CH}_{3} \mathrm{CO}_{2}^{-}(a q)=>\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)+\mathrm{Cl}^{-}(a q) \end{array} \] Question 6 A buffer solution made from acetic acid \( \left(\mathrm{HCH}_{3} \mathrm{CO}_{2}\right) \) and sodium acetate \( \left(\mathrm{NaCH}_{3} \mathrm{CO}_{2}\right) \) was titrated with sodium hydroxide. What is the net ionic equation for the reaction? \[ \begin{array}{l} \mathrm{NaOH}(a q)+\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)=>\mathrm{H}_{2} \mathrm{O}(l)+\mathrm{NaCH}_{3} \mathrm{CO}_{2}(a q) \\ \mathrm{Cl}^{-}(\mathrm{aq})+\mathrm{Na}^{+}(\mathrm{aq})=>\mathrm{NaCl}(\mathrm{aq}) \\ \mathrm{H}_{3} \mathrm{O}^{+}(\text {aq })+\mathrm{OH}^{-}(\mathrm{aq})=>2 \mathrm{H}_{2} \mathrm{O}(l) \end{array} \] \[ \mathrm{OH}^{-}(a q)+\mathrm{CH}_{3} \mathrm{CO}_{2}^{-}(a q)=>\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)+\mathrm{O}^{2-}(a q) \] \[ \mathrm{OH}^{-}(a q)+\mathrm{HCH}_{3} \mathrm{CO}_{2}(a q)=>\mathrm{H}_{2} \mathrm{O}\left(()+\mathrm{CH}_{3} \mathrm{CO}_{2}{ }^{-}(a q)\right. \]
