## Latimer Diagram for Iron in Acidic Solution
The Latimer diagram for iron in acidic solution shows the standard reduction potentials for various iron species under acidic conditions (pH
FeO42- (0.77 V) Fe3+ (0.77 V) Fe2+ (0.44 V) Fe
Explanation:
FeO42- (ferrate(VI) ion) is the most oxidized form of iron shown here. The potential for its reduction to Fe3+ is 0.77 V.
Fe3+ (ferric ion) has a standard reduction potential of 0.77 V, indicating that it is readily reduced to Fe2+.
Fe2+ (ferrous ion) has a standard reduction potential of 0.44 V, making it less readily reduced than Fe3+.
Fe (metallic iron) is the most reduced form of iron in this diagram.
Note: The Latimer diagram can be used to determine the relative stability of different oxidation states of iron under acidic conditions.
