In fact, acidic salts are formed after the reaction between strong acid and weak base. So, When HCl reacts with ammonium hydroxide to formammonium chloride (NH4Cl) and water where ammonium chloride which is an acidic salt.

Introduction:

HCl, or hydrochloric acid, is a strong acid commonly used in various industries and laboratory settings. It is a highly corrosive and reactive compound that dissociates completely in water, releasing hydrogen ions (H+) and chloride ions (Cl-). Despite its strong acidic properties, HCl does not form an acidic salt. This can be explained by considering the nature of the acid and the salt formation process.

Explanation:

1. Acidic salts:
Acidic salts are formed when a weak acid reacts with a strong base. In this reaction, the weak acid partially loses a hydrogen ion (proton) and forms a negatively charged ion called a conjugate base. The strong base then combines with this conjugate base to form the acidic salt. The resulting salt has both acidic and basic properties, with the acidic nature predominating.

2. Hydrochloric acid (HCl):
HCl is a strong acid due to its ability to completely ionize in water. It donates all its hydrogen ions to the solution, leaving behind chloride ions. Since HCl is already a strong acid, it does not have a conjugate base that can react with a strong base to form an acidic salt.

3. Complete ionization:
When HCl is dissolved in water, it undergoes complete ionization, meaning that all the HCl molecules dissociate into H+ and Cl- ions. This complete ionization leaves no undissociated HCl molecules in the solution, which are necessary for the formation of an acidic salt. In other words, there is no weak acid component remaining to react with a strong base and form an acidic salt.

4. Formation of chloride salts:
Instead of forming an acidic salt, HCl typically forms chloride salts when it reacts with a base. For example, when HCl reacts with sodium hydroxide (NaOH), sodium chloride (NaCl) is formed. In this reaction, the hydrogen ion from HCl combines with the hydroxide ion from NaOH to form water, and the remaining chloride ion combines with the sodium ion to form NaCl.

Conclusion:

In summary, HCl does not form an acidic salt because it is already a strong acid that completely ionizes in water, leaving no undissociated molecules to react with a strong base. Instead, it typically forms chloride salts when reacting with bases.
