Question

Write the equation to represent the reaction of Sodium hydroxide (iii) with hydrochloric acid

Answer 1

1. Chemical equation

The representation of a chemical reaction along with the reaction conditions and physical state of compounds, as well as, reactants and products separated by an arrow is called a chemical equation.

2. Reaction of Sodium hydroxide

(iii) Sodium hydroxide (base) in reaction with Hydrochloric acid (acid) gives Sodium chloride (salt) and Water. The reaction is an example of a neutralization reaction and a type of double displacement reaction.
The chemical equation for the reaction of Sodium hydroxide with Hydrochloric acid is given below.

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