Q
Q: Which of the following acids is a strong acid in aqueous solution?
Solution: HCl is a strong acid that completely dissociates in water, while HF, H2CO3, and CH3COOH are weak acids.
Steps: 5
Step 1: Understand what a strong acid is. A strong acid is one that completely breaks apart (dissociates) into ions when dissolved in water.
Step 2: Look at the acids given in the question: HCl, HF, H2CO3, and CH3COOH.
Step 3: Identify which of these acids is known to be a strong acid. HCl (hydrochloric acid) is a strong acid.
Step 4: Check the other acids: HF (hydrofluoric acid), H2CO3 (carbonic acid), and CH3COOH (acetic acid) are all weak acids, meaning they do not completely dissociate in water.
Step 5: Conclude that HCl is the only strong acid among the options provided.
