The correct Answer is:
To solve the question regarding the two statements about strong monoprotic acids and the leveling effect of water, we can break down the solution into clear steps: ### Step-by-Step Solution: **Step 1: Understand the concept of strong monoprotic acids.** - Strong monoprotic acids are acids that completely dissociate in solution to release one proton (H⁺) per molecule. Examples include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and nitric acid (HNO₃). **Step 2: Analyze Statement 1.** - Statement 1 claims that all strong monoprotic acids with the same concentration in dilute solution show the same pH. Since strong acids completely dissociate, the concentration of H⁺ ions in solution will be equal to the concentration of the acid. Therefore, if all acids are at the same concentration, they will produce the same concentration of H⁺ ions, resulting in the same pH. **Step 3: Analyze Statement 2.** - Statement 2 states that water shows the leveling effect. The leveling effect refers to the phenomenon where the strength of strong acids is limited by the solvent (in this case, water). In water, all strong acids will produce hydronium ions (H₃O⁺) to the same extent, which means that their effective strength is leveled out. This is because water can only stabilize a certain concentration of H⁺ ions. **Step 4: Connect the statements.** - The leveling effect (Statement 2) explains why all strong monoprotic acids at the same concentration yield the same pH in dilute solutions (Statement 1). The pH is determined by the concentration of H⁺ ions, which is the same for all strong acids in water due to the leveling effect. **Step 5: Conclusion.** - Both statements are correct, and Statement 2 correctly explains Statement 1. Therefore, the answer is that both statements are true, and Statement 2 is the correct explanation for Statement 1. ### Final Answer: Both statements are correct, and Statement 2 is the correct explanation for Statement 1. ---
