Question

Which of the following pair(s) will not undergo neutralizaion reaction?

• A. $\text{HCl}$ and ${\text{H}}_2{\text{SO}}_4$
• B. ${\text{H}}_2{\text{SO}}_4$ and $\text{NaCl}$
• C. $\text{HCl}$ and $\text{KOH}$
• D. $\text{NaOH}$ and $\text{KCl}$

Answer 1

The correct option is C $\text{HCl}$ and $\text{KOH}$

The process in which acid and base react to form salt and water is called neutralization reaction.
In the given options, $\text{HCl}$ and ${\text{H}}_2{\text{SO}}_4$ are acids. $\text{KOH}$ and $\text{NaOH}$ are bases and $\text{KCl}$ and $\text{NaCl}$ are salts. As neutralization is an acid base reaction, only the reaction between $\text{HCl}$ and $\text{KOH}$ is a neutralization reaction.
