Which reaction represents an acid-base neutralization reaction? Hint: How do you identify acids and bases? \[ \begin{array}{c} 2 \mathrm{NaOH}+\mathrm{MgSO}_{4} \\ \longrightarrow \mathrm{Na}_{2} \mathrm{SO}_{4}+\mathrm{Mg}(\mathrm{OH})_{2} \\ \mathrm{HNO}_{3}+\mathrm{KOH} \\ \mathrm{KNO}_{3}+\mathrm{H}_{2} \mathrm{O} \\ \mathrm{H}_{2} \mathrm{O}+\mathrm{H}_{2} \mathrm{SO}_{4} \\ \longrightarrow \\ \mathrm{H}_{3} \mathrm{O}^{+}+\mathrm{HSO}_{4} \\ \mathrm{NaNO}_{3}+\mathrm{LiOH}_{3} \end{array} \]
