Question

Of the following, which forms a neutral solution? Assume all acids and bases are combined in stoichiometrically equivalent amounts.

HCN(aq)+KOH(aq)⇌KCN(aq)+H2O(l)

H2S(aq)+2LiOH(aq)⇌Li2S(aq)+2H2O(l)

CH3CO2H(aq)+NaOH(aq)⇌NaCH3CO2(aq)+H2O(l)

2HNO3(aq)+Sr(OH)2(aq)⇌Sr(NO3)2(aq)+2H2O(l)

Answer 1

2HNO3(aq)+Sr(OH)2(aq)⇌Sr(NO3)2(aq)+2H2O(l)

This is a reaction of a strong acid, HNO₃and a strong base, Sr(OH)₂, which results in formation of a neutral salt, Sr(NO₃)₂. All the other reactions are weak acids plus strong bases producing alkaline salts.
