Given that I2+2e- arrow 2I ominus;E ominus=0.54 V Br2+2e- arrow 2Br ominus;E ominus=1.69 V Predict which of the following is true (A) I ominus ions will be able to reduce bromine (B) Br ominus ions will be able to reduce iodine (C) Iodine will be able to reduce bromine (D) Bromine will be able to reduce iodide ions

Since the reduction potential of Br2|.2Br ominus is greater than the reduction potential of I2|.2I ominus , so I ominus ions will reduce Br2 .

Q. 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

$I^{⊖}$ ions will be able to reduce bromine

$B r^{⊖}$ ions will be able to reduce iodine

Iodine will be able to reduce bromine

Bromine will be able to reduce iodide ions

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 $B r_{2}$ .
