Consult the table of standard electrode potentials and suggest three substances that can oxidise ferrous ions under suitable conditions.

Text Solution

Verified by Experts

For the half - cell reaction : `Fe^(3+)(aq)+e rarr Fe^(2+)(aq)`, the standard reduction potential is `+0.77V`. Hence, those substance which have standard reduction potential greater than `+0.77V` will be able to oxidise `Fe^(2+)` ions under standard conditions. Three such substance are : `Ag^(+), Cl_(2), Br_(2)`.
