From what I remember, the more positive the potential, the better the oxidizing agent.

i have some standard electrode values.

OCl[tex]^{-}_{(aq)}[/tex] + H[tex]^{+}_{(aq)}[/tex] + e[tex]^{-}[/tex] [tex]\Leftrightarrow[/tex] [tex]\frac{1}{2}[/tex]Cl[tex]_{2(aq)}[/tex] + 2H[tex]_{2}[/tex]O[tex]_{(l)}[/tex]

emf = + 1.64 V

NO[tex]^{-}_{3(aq)}[/tex] + 3H[tex]^{+}_{(aq)}[/tex] + 2e[tex]^{-}[/tex] [tex]\Leftrightarrow[/tex] HNO[tex]_{2(aq)}[/tex] + H[tex]_{2}[/tex]O[tex]_{(l)}[/tex]

emf = + 0.94 V

therefore, the chlorate(1) is a stronger oxidising agent.

Chlorate isi have some standard electrode values.

OCl[tex]^{-}_{(aq)}[/tex] + H[tex]^{+}_{(aq)}[/tex] + e[tex]^{-}[/tex] [tex]\Leftrightarrow[/tex] [tex]\frac{1}{2}[/tex]Cl[tex]_{2(aq)}[/tex] + 2H[tex]_{2}[/tex]O[tex]_{(l)}[/tex]

emf = + 0.94 V

therefore, the chlorate(1) is a stronger oxidising agent.

[tex]ClO_3^{-}[/tex]

not

[tex]ClO^{-}[/tex]

Does this mean it is 1.7x stronger?emf = + 1.64 V

emf = + 0.94 V

therefore, the chlorate(1) is a stronger oxidising agent.
