→ Consult the table of standard electrode potentials and suggest three substances that can oxidize free !

$\huge{\tt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}$

→ Substances that are stronger oxidising agents than ferrous ions can oxidise ferrous ions. This implies that the substances having higher reduction potentials than +0.77 V can oxidise ferrous ions to ferric ions. Three substances that can do so are

$\tt{F_2, Cl_2, and \: \: O_2.}$
