💡 Analysis & Explanation
Salt Hydrolysis Principle ▼
When dissolved in water, salts formed by the combination of a strong acid and a weak base inherently yield an acidic solution.
Chemical Composition ▼
Ammonium chloride (NH₄Cl) is a classic pedagogical example of this, being derived from hydrochloric acid (a very strong acid) and ammonium hydroxide (a weak base).
Aqueous Reaction ▼
Upon dissolution, the ammonium ion undergoes hydrolysis to release excess hydrogen ions (H+) into the solution, thereby lowering its pH level.
Conclusion ▼
Therefore, NH₄Cl naturally forms a slightly acidic solution.
