To be an oxidation ,there, must be a reduction. We look what happen to ,K2Cr2O7,(potassium dichromate) We can use (Cr2O4)²- as ,K2Cr2O7,. This is the half reaction (Cr2O4)²- + 8H+ 6e 2Cr³+ + 4(H20) It is a oxidation reaction. It means the S in SO2 becomes reduced. This is the half reaction. SO2 + 2(H20) (SO4)²- + 4H+ 2e. Here SO2 becomes (SO4)²-
