Question

Neutralisation reaction is an example of ______ reaction.

• A. Endothermic
• B. Exothermic
• C. Decomposition
• D. None of the above

Answer 1

Correct option: (A)

Neutralization reaction: Neutralization is a chemical reaction in which an acid reacts with a base to form salt and water.

In other words, it can be said that neutralization is the combination of hydrogen ions and hydroxide ions to produce salt and water.

Example: The reaction between hydrochloric acid $\left(HCl\right)$ and Sodium hydroxide$\left(NaOH\right)$ leads to the production of sodium chloride$\left(NaCl\right)$ and water$\left(H_{2}O\right)$.

$HCl\left(aq\right)+NaOH\left(aq\right)⟶NaCl\left(s\right)+H_{2}O\left(l\right)$

Generally, In the case of a neutralization reaction heat is released. So it is an example of the exothermic reaction.

Hence, the correct option is (A)
