Statement-1: It is difficult to distinquish the strengths of the strong acids such as `HCl, H_2SO_4,HNO_3, HBr, HI or HCIO_4` in dilute aqueous solutions.
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_3O^(+)` ions plus the anions of strong acid.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Explanation

To solve the question, we need to analyze both statements and determine their validity and relationship.

### Step 1: Analyze Statement 1
Statement 1 claims that it is difficult to distinguish the strengths of strong acids like HCl, H₂SO₄, HNO₃, HBr, HI, or HClO₄ in dilute aqueous solutions.

**Explanation:**
- Strong acids are defined as acids that completely dissociate in water.
- In dilute solutions, all these strong acids dissociate fully to produce hydronium ions (H₃O⁺) and their respective anions.
- Since they all produce H₃O⁺ ions in similar concentrations, it becomes challenging to differentiate their strengths based solely on the concentration of H₃O⁺ ions.

### 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 to produce a solution containing H₃O⁺ ions plus the anions of the strong acid.

**Explanation:**
- This statement is accurate because strong acids do indeed donate protons (H⁺) to water, forming hydronium ions (H₃O⁺).
- The complete ionization means that the concentration of H₃O⁺ ions is equal to the concentration of the strong acid initially present in the solution.

### Step 3: Determine the Relationship Between the Statements
- Since Statement 2 provides a correct explanation for Statement 1, both statements are true.
- Statement 1 describes the difficulty in distinguishing the strengths due to complete ionization, while Statement 2 explains why this is the case.

### Conclusion
Both statements are true, and Statement 2 correctly explains Statement 1.

### Final Answer
- **Statement 1 is true.**
- **Statement 2 is true and provides the correct explanation for Statement 1.**
