What is the neutralisation equation in detail?

The neutralization equation represents the chemical reaction between an acid and a base, resulting in the formation of water and a salt. The general form of the equation can be expressed as:

[ \text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water} ]

For example, in the neutralization of hydrochloric acid (HCl) with sodium hydroxide (NaOH), the equation is:

[ \text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H}_2\text{O} ]

This demonstrates how the hydrogen ions (H⁺) from the acid react with hydroxide ions (OH⁻) from the base to produce water (H₂O).
