Answer 1

The reaction represented by HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l) is called a neutralization reaction, which is the reaction of an acid with a base to form salt and water.

Step-by-step explanation:

The chemical reaction HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l) is an example of a neutralization reaction. This type of reaction occurs when an acid and a base react to form water and a salt. Specifically, hydrochloric acid (HCl) and sodium hydroxide (NaOH) combine to produce sodium chloride (NaCl) and water (H₂O). In such a reaction, neutralization leads to the formation of water, as hydrogen ions (H+) from the acid react with hydroxide ions (OH-) from the base, resulting in the creation of water molecules.

Moreover, in aqueous solution, the complete ionic equation shows all strong electrolytes as ions:

H+ (aq) + Cl¯ (aq) +Na+ (aq) +OH¯(aq) → Na+ (aq) + Cl¯ (aq) +H₂O(l)

The sodium and chloride ions act as spectator ions and do not participate directly in the reaction, leading to the net ionic equation:

H+ (aq) + OH(aq) → H₂O (l)
