The name of the chemical reaction between an acid and a base is:
b) Neutralization
Neutralization is the process where an acid and a base react with each other to form water and a salt. This reaction occurs when the hydrogen ions from the acid combine with the hydroxide ions from the base to form water molecules. The remaining ions form a salt. This reaction helps neutralize the acidic and basic properties of the substances involved, resulting in a solution that is neither acidic nor basic but neutral.
For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the neutralization reaction produces water (H2O) and sodium chloride (NaCl), which is common table salt:
HCl + NaOH → H2O + NaCl
