Step-by-Step Explanation 1. Overview of Acid Strength Acid strength is determined by the ease with which an acid donates a proton ($H^+$). A stronger acid dissociates more completely in water to release $H^+$ ions. 2. Identifying the Acids The four options represent commonly known acids: Hydrochloric acid ($HCl$) Nitric acid ($HNO_3$) Sulfuric acid ($H_2SO_4$) Acetic acid ($CH_3COOH$) 3. Relative Strength of the Acids Hydrochloric acid ($HCl$): A strong acid, fully ionizes in water. Nitric acid ($HNO_3$): Also a strong acid, fully ionizes. Sulfuric acid ($H_2SO_4$): Considered one of the strongest acids; in its first ionization step, it dissociates completely, releasing a proton with high ease. The second ionization also contributes to its overall acidity. Acetic acid ($CH_3COOH$): A weak acid; only partially dissociates in water. 4. Conclusion Among the given choices, sulfuric acid ($H_2SO_4$) is the strongest acid due to its high degree of ionization and ability to donate two protons. Hence, the correct answer is:
