Given that

$I_{2} + 2 e^{-} \to 2 I^{⊖}; E^{⊖} = 0.54$ V
$B r_{2} + 2 e^{-} \to 2 B r^{⊖}; E^{⊖} = 1.69$ V

Predict which of the following is true

Options:

Answer:

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 $B r_{2}$ .
