Method II:
Preparation of carbon monoxide from ethanedioic acid (exalic acid crystals.) H2C2O4
Crystals of exilic acid are put in a flask and concentrated sulphuric acid is added and the mixture is heated. Hot concentrated sulphuric acd dehydrates exalic acid crystals to give a mixture of carbon dioxide and carbon monoxide.
The gases are bubbled through concentrated potassium hydroxide solution to absorb carbon dioxide gas. (carbon monoxide is collected over water.)
Both gases are colourless
Have no smell
And don’t support combustion.
