Statement 1: The standard reduction potentials (SRP) of three metal ions A⁺, B²+, and C³+ are -0.3 V, -0.5 V, and 0.8 V respectively. Therefore, the oxidising power order is: C³+ > A⁺ > B²+. Statement 2: A higher SRP corresponds to a stronger oxidising agent.
- Statement 1 is true, Statement 2 is true, and Statement 2 is the correct explanation of Statement 1.
- Statement 1 is true, Statement 2 is true, but Statement 2 is NOT the correct explanation of Statement 1.
- Statement 1 is true, Statement 2 is false.
- Statement 1 is false, Statement 2 is true.
Correct answer: Statement 1 is true, Statement 2 is true, and Statement 2 is the correct explanation of Statement 1.
Solution
Statement 2 is correct: higher SRP means the ion is more easily reduced, hence a stronger oxidising agent. Ranking by SRP: C³+(0.8 V) > A^+(-0.3 V) > B²+(-0.5 V), confirming Statement 1. Statement 2 directly explains Statement 1.
