Which equation represents a neutralization reaction?
HCl(aq)+NH3(aq)NH4Cl(aq)\mathrm{HCl}_{(\mathrm{aq})}+\mathrm{NH}_{3(\mathrm{aq})} \rightleftharpoons \mathrm{NH}_{4} \mathrm{Cl}_{(\mathrm{aq})}
Pb2+(aq)+2Cl(aq)PbCl2( s)\mathrm{Pb}^{2+}{ }_{(\mathrm{aq})}+2 \mathrm{Cl}_{(\mathrm{aq})}^{-} \rightleftharpoons \mathrm{PbCl}_{2(\mathrm{~s})}
Bal2(aq)+MgSO4(aq)BaSO4( s)+Mgl2(aq)\mathrm{Bal}_{2(\mathrm{aq})}+\mathrm{MgSO}_{4(\mathrm{aq})} \rightleftharpoons \mathrm{BaSO}_{4(\mathrm{~s})}+\mathrm{Mgl}_{2(\mathrm{aq})}

A
Key Concept
Neutralization Reaction
Explanation
A neutralization reaction occurs when an acid and a base react to form water and a salt. In the given options, the reaction between hydrochloric acid (HCl(aq)\mathrm{HCl}_{(\mathrm{aq})}) and ammonia (NH3(aq)\mathrm{NH}_{3(\mathrm{aq})}) produces ammonium chloride (NH4Cl(aq)\mathrm{NH}_{4}\mathrm{Cl}_{(\mathrm{aq})}), which is a typical example of a neutralization reaction.
