Here are the oxidations using dichromate ion, a commonly used oxidizing agent in organic chemistry:
Partial oxidation to aldehydes
3 CH3CH2OH + Cr2O72�?/SUP> + 8 H+ ––�?gt; 3 CH3CHO + 2 Cr3+ + 7 H2O
Full oxidation to carboxylic acids
3 CH3CH2OH + 2 Cr2O72�?/SUP> + 16 H+ ––�?gt; 3 CH3COOH + 4 Cr3+ + 11 H2O
