Which of these neutralization reactions has a pH = 7 when equal molar amounts of acid and base are mixed? A)CH₃CO₂H(aq)+ LiOH(aq)⇌ H₂O(l)+ LiCH₃CO₂(aq) B)HI(aq)+ C₅H₅N(aq)⇌ C₅H₅NHI(aq) C)HI(aq)+ KOH(aq)⇌ H₂O(l)+ KI(aq) D)HNO₂(aq)+ NH₃(aq)⇌ NH₄NO₂(aq)

Question

Quizplus · Accepted Answer

The neutralization reaction between an acid and a base produces salt and water. When equal molar amounts of acid and base are mixed, the pH of the resulting solution will be 7 if the acid and base are strong. In option C, both HI and KOH are strong acids and bases, respectively, and hence will produce a salt (KI) and water. Therefore, Option C is the best choice for the neutralization reaction with a resulting pH of 7.
