Step 1: Define strong and weak acids A strong acid undergoes complete ionization in water, yielding its constituent ions. A weak acid exhibits incomplete ionization. Step 2: Classify acids - \( \text{H}_2\text{SO}_4 \) (Sulfuric acid) is classified as a strong acid due to its complete dissociation in aqueous solution. - \( \text{CH}_3\text{COOH} \) (Acetic acid) is identified as a weak acid, as it only partially dissociates. - \( \text{H}_2\text{CO}_3 \) (Carbonic acid) is also a weak acid, exhibiting partial dissociation. - \( \text{HNO}_3 \) (Nitric acid) is a strong acid; however, \( \text{H}_2\text{SO}_4 \) is the correct choice for this specific question. Answer: The correct choice is option (1): \( \text{H}_2\text{SO}_4 \).
