(1) From the half-reaction formulas ① and ②, express the ionic
equation of the redox reaction.
→ Eliminate e− from the equations
① and ② and combine them into one equation.
(2) Find the oxidation numbers of chromium(Cr) and oxygen(O) of
red letters.

Note: Cr2O72− ,
H2O2, O2 have two Cr atoms and two
O atoms in the chemical formula, so calculate the oxidation number
per atom.
Cr2

Cr3+
