Combustion of CO in O2 or air, in presence of Pd and H2O, has been explained by assuming the formation of H2O2 and the simultaneous formation of CO2 and H2O2 from CO, H2O, and O2. This oxidation is not dependent upon O2 of air, but takes place thus: CO+H2O=CO2+H2. The 1st product is HCOOH, which decomposes into CO2 and H2, the latter once more forming H2O and O2 of air. The presence of HCOOH may be shown by directing a CO flame upon ice, neutralizing the water formed with Ba(OH)2, filtering, and testing with AgNO3.
