Chemistry
Give reasons for the following:
An aqueous solution of the salt ammonium chloride is acidic in nature while an aqueous solution of sodium chloride is neutral.
Answer
As ammonium chloride is a salt of a weak alkali and strong acid, hence it's aqueous solution is acidic in nature. On the other hand, sodium chloride is a product of strong alkali and strong acid hence, it's aqueous solution is neutral in nature.
| Neutralization reaction | Base + Acid | Salt | + water | Nature |
|---|---|---|---|---|
| Weak alkali + strong acid | NH4OH + HCl | ⟶ NH4Cl | + H2O | acidic |
| Strong alkali + strong acid | NaOH + HCl | ⟶ NaCl | + H2O | neutral |
