Question

What are the reduction potentials of the halogens?

Answer 1

Because the halogens are excellent oxidants......

Explanation:

Fluorine is the most reactive element on the Periodic Table. Chlorine and bromine is also exceptionally reactive. Elemental bromine, a liquid, and iodine are also reactive species.

`X_2+2e^(-)rarr2X^-`

And in terms of standard reduction potential.....

`1/2X_2 + e^(-) rarr X^-`,

`E^@=+2.87(F); +1.36(Cl);+1.08(Br); +0.535(I)`
