| Assertion (A): | The standard reduction potentials of three metallic ions A, B, and C are –0.3, –0.5, and 0.8 volts respectively. Therefore, the oxidizing power of ions is C > A > B. |
| Reason (R): | The higher the standard reduction potential, the higher the oxidizing power. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
