H2C2O4 → CO + CO2 + H2O - Chemical Equations Online!

This is an oxidation-reduction (redox) reaction:

CIII+e-→CII(reduction)

CIII-1e-→CIV(oxidation)

H2C2O4 is both an oxidizing and a reducing agent (disproportionation (dismutation)).

This is a gas evolution reaction, CO and CO2 is the formed gas.
