Question

Write the balanced chemical equation to show the formation of the following salts by neutralization reaction :

NaCl

Answer 1

1. Neutralization reaction

A reaction between an acid and a base that forms salt and water is called a neutralization reaction. During the reaction, the protons from the acid and the hydroxide ions from the base react to form water. Salt is an ionic compound that gives ions other than hydrogen protons and hydroxide ions in solution.

2. Formation of Sodium chloride

Sodium chloride $\left(\mathrm{NaCl}\right)$ is a salt that contains Sodium ions $\left({\mathrm{Na}}^{+}\right)$ and Chloride ions $\left({\mathrm{Cl}}^{-}\right)$. Therefore, it is formed by the reaction between an acid containing chloride ions like Hydrochloric acid $\left(\mathrm{HCl}\right)$ and a base containing sodium ions like Sodium hydroxide $\left(\mathrm{NaOH}\right)$.

The balanced equation for the reaction can be given as:

$$\begin{gathered} \mathrm{HCl}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ (\mathrm{Hydrochloric}(\mathrm{Sodium}(\mathrm{Sodium}(\mathrm{Water}) \\ \mathrm{acid})\mathrm{hydroxide})\mathrm{chloride}) \end{gathered}$$
