Given that I 2 + 2 e - → 2 I ⊖ ; E ⊖ = 0.54 V B r 2 + 2 e - → 2 B r ⊖ ; E ⊖ = 1.69 V Predict which of the following is true
Options
- AI ⊖ ions will be able to reduce bromine
- BB r ⊖ ions will be able to reduce iodine
- CIodine will be able to reduce bromine
- DBromine will be able to reduce iodide ions
Correct answer
A. I ⊖ ions will be able to reduce bromine
Step-by-step solution
Since the reduction potential of B r 2 | 2 B r ⊖ is greater than the reduction potential of I 2 | 2 I ⊖ , so I ⊖ ions will reduce B r 2 .
