When a copper wire is immersed in a solution of AgNO3, the colour of solution becomes blue because copper:
1. forms a soluble complex with AgNO3
2. is oxidised to Cu2+
3. is reduced to Cu2-
4. splits up into atoic form and dissolves

| 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). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
