Question

Which one of the following is strong acid ?

• A. CH₃COOH
• B. HCL
• C. H₂O
• D. NH₄OH

Answer 1

The Correct Option is B

To solve this question, we need to identify which of the following compounds is a strong acid.

1. Understanding the Acids:
- CH₃COOH (Acetic Acid): A weak acid, commonly found in vinegar. It partially dissociates in water.
- HCl (Hydrochloric Acid): A strong acid, fully dissociates in water, commonly used in laboratories and industries.
- H₂O (Water): Neutral, neither an acid nor a base.
- NH₄OH (Ammonium Hydroxide): A weak base, not an acid.

2. Identifying the Strong Acid:
Among the options, HCl is a strong acid as it completely dissociates in water, releasing hydrogen ions (H⁺) without any equilibrium.

Final Answer:
Option (B) HCl is the strong acid.
