Question

Which of the following acids is a strong acid?

• A. \( \text{H}_2\text{SO}_4 \)
• B. \( \text{CH}_3 \text{COOH} \)
• C. \( \text{H}_2 \text{CO}_3 \)
• D. \( \text{HNO}_3 \)

Hint:

Remember: Strong acids dissociate completely in water, while weak acids only partially dissociate.

Answer 1

The Correct Option is A

Step 1: Understand the concept of strong and weak acids A strong acid is one that completely dissociates into its ions in water. A weak acid only partially dissociates. Step 2: Identify the strong acids - \( \text{H}_2\text{SO}_4 \) (Sulfuric acid) is a strong acid because it dissociates completely in water. - \( \text{CH}_3\text{COOH} \) (Acetic acid) is a weak acid because it only partially dissociates. - \( \text{H}_2\text{CO}_3 \) (Carbonic acid) is a weak acid because it also only partially dissociates. - \( \text{HNO}_3 \) (Nitric acid) is a strong acid, but the correct option here is \( \text{H}_2\text{SO}_4 \). Answer: The correct answer is option (1): \( \text{H}_2\text{SO}_4 \).
