### Acids and Their Strengths #### Question: Which of the following is not a strong acid? #### Options: 1. \(\ce{HNO3}\) 2. \(\ce{H2SO4}\) 3. \(\ce{HClO4}\) 4. \(\ce{H3PO4}\) 5. **All are strong acids.** - **Option 1:** \(\ce{HNO3}\) - Nitric Acid - **Option 2:** \(\ce{H2SO4}\) - Sulfuric Acid - **Option 3:** \(\ce{HClO4}\) - Perchloric Acid - **Option 4:** \(\ce{H3PO4}\) - Phosphoric Acid - **Option 5:** All are strong acids. **Explanation:** Among the acids listed, \(\ce{HNO3}\) (Nitric Acid), \(\ce{H2SO4}\) (Sulfuric Acid), and \(\ce{HClO4}\) (Perchloric Acid) are known to be strong acids. They almost completely dissociate in water, releasing a large number of hydrogen ions (\(\ce{H+}\)). In contrast, \(\ce{H3PO4}\) (Phosphoric Acid) is considered a weak acid. It does not fully dissociate in water, meaning it only partially releases hydrogen ions. Therefore, the correct answer is: \(\ce{H3PO4}\) (Phosphoric Acid)
