My teacher give me the equation and im going crazy, its a redox btw:


CH3-CH2-CH2-OH + Cr2O7K2 + SO4H2  :rarrow: propanoic acid + Cr2(SO4)3 + SO4K2 + H2O

What is being oxidised, and what is being reduced? Can you write half equations for each?

Consider then

RCH2OH -> RCO2H in the presence of acid (the ethyl is unchanged so we can ignore it for simplification). Can you balance this?
