Strong Base
- A strong base is a substance that completely dissociates in water to produce hydroxide ions (OH⁻).
- Example: Sodium Hydroxide (NaOH)
- It dissolves fully in water, increasing the concentration of OH⁻ ions.
- Commonly used in cleaning products and drain cleaners.

Weak Base
- A weak base only partially dissociates in solution, resulting in a lower concentration of hydroxide ions.
- Example: Ammonia (NH₃)
- It reacts with water to form hydroxide ions but does not fully dissociate.
- Used in fertilizers and household cleaners.

Strong Acid
- A strong acid completely ionizes in water, releasing a large amount of hydrogen ions (H⁺).
- Example: Hydrochloric Acid (HCl)
- It dissociates fully in water, increasing H⁺ concentration significantly.
- Commonly found in gastric acid and used in various industrial processes.

Weak Acid
- A weak acid only partially ionizes in solution, resulting in fewer hydrogen ions compared to strong acids.
- Example: Acetic Acid (CH₃COOH)
- It is found in vinegar and only a fraction of acetic acid molecules dissociate into ions.
- Used in food preservation and flavoring.

Summary
Understanding the differences between strong and weak acids and bases is crucial:
- Strong bases like NaOH fully dissociate, while weak bases like NH₃ do not.
- Strong acids like HCl completely ionize, whereas weak acids like CH₃COOH only partially do.
- These properties affect their behavior in chemical reactions and their applications in everyday life.
