Solution and Explanation

Step 1: Acidic Salt:
An acidic salt is formed when a strong acid reacts with a weak base, and it contains replaceable hydrogen ions (H+).
- Name: Ammonium chloride
- Formula: NH₄Cl
- Parent acid: Hydrochloric acid (HCl)
- Parent base: Ammonia (NH₃)

Step 2: Basic Salt:
A basic salt is formed when a weak acid reacts with a strong base, and it contains hydroxide ions (OH−) in addition to the cation from the base.
- Name: Sodium carbonate
- Formula: Na₂CO₃
- Parent acid: Carbonic acid (H₂CO₃)
- Parent base: Sodium hydroxide (NaOH)

Step 3: Conclusion:
- An acidic salt example is ammonium chloride (NH₄Cl), formed from hydrochloric acid and ammonia.
- A basic salt example is sodium carbonate (Na₂CO₃), formed from carbonic acid and sodium hydroxide.
