`Br_(2)` and `I_(2)` are added to a solution containing `1M` each of `Br^(c-)` and `I^(c-)` . What reaction will occur ?

Options

A. Iodine will reduce bromide ions
B. Bromine will reduce iodide ions
C. Iodide ions will reduce bromine
D. Bromide ions will reduce iodine .

Answer

C

Explanation

Lower SRP `to` Anode - Oxidation
`2 I^(-) to I_(2) + 2e^(-)`
Higher SRP `to` Cathode - Reduction
`therefore Br_(2) + 2e^(-) to 2 Br^(-)`
