STATEMENT-2: It is difficult to distinguish between the strenghts of the strong acids like HCl, `HNO_(3), HClO_(4)` etc. in dilute aqueous solution.
STATEMENT-2 : In dilute aqueous solution, all strong acids donate a proton to water and are essentially `100%` ionised to produce a solution containing `H_(3)O^(+)` ions plus t he anions of strong acid.

The correct Answer is:
To solve the question, we need to analyze both statements provided and determine their validity. ### Step-by-Step Solution: **Step 1: Analyze Statement 1** - Statement 1 claims that it is difficult to distinguish between the strengths of strong acids like HCl, HNO3, HClO4, etc., in dilute aqueous solutions. - Strong acids are defined as acids that completely dissociate in water, meaning they release all their protons (H⁺ ions) into the solution. **Hint for Step 1:** Consider how the strength of an acid is typically measured and how complete dissociation affects this measurement. **Step 2: Analyze Statement 2** - Statement 2 states that in dilute aqueous solutions, all strong acids donate a proton to water and are essentially 100% ionized, producing a solution containing H₃O⁺ ions and the anions of the strong acid. - This is true because strong acids like HCl, HNO3, and HClO4 completely dissociate in water, leading to the formation of hydronium ions (H₃O⁺) and their respective anions. **Hint for Step 2:** Think about the concept of ionization and how it relates to the concentration of H⁺ ions in the solution. **Step 3: Conclusion on the Statements** - Since all strong acids in dilute solutions produce the same concentration of H₃O⁺ ions, the pH of the solutions will be the same, making it difficult to distinguish between their strengths based solely on pH. - Therefore, both statements are correct: Statement 1 is true because we cannot distinguish between the strengths of strong acids in dilute solutions, and Statement 2 is true because it accurately describes the behavior of strong acids in water. **Hint for Step 3:** Reflect on how the properties of strong acids lead to similar behaviors in solution, impacting their classification based on pH. ### Final Answer: Both statements are correct. Statement 1 is true, and Statement 2 is also true, as it explains why Statement 1 is valid.
