Question

Which of the following is a strong acid?

• A. Acetic acid
• B. Hydrochloric acid
• C. Carbonic acid
• D. Formic acid

Answer 1

The Correct Option is B

In the category of acids, they are typically classified based on their ability to dissociate in water and release hydrogen ions (H⁺). A strong acid is one that completely dissociates in solution, meaning it effectively releases all of its possible hydrogen ions.

Consider the options:

• Acetic acid (CH₃COOH): A weak acid, as it partially dissociates in solution.
• Hydrochloric acid (HCl): A strong acid, fully dissociating in water.
• Carbonic acid (H₂CO₃): Considered a weak acid, as it only partially ionizes.
• Formic acid (HCOOH): Similar to acetic acid, it is a weak acid due to partial dissociation.

Of the options provided, Hydrochloric acid is the strong acid, known for its complete dissociation in aqueous solutions.
