Here's the balanced chemical equation:
H₂C₂O₄ (s) + H₂SO₄ (l) → CO (g) + CO₂ (g) + H₂O (l) + H₂SO₄ (l)
Explanation:
* Oxalic acid (H₂C₂O₄) acts as the reactant.
* Concentrated sulfuric acid (H₂SO₄) acts as a dehydrating agent. It removes water molecules from the oxalic acid.
* Carbon monoxide (CO) and carbon dioxide (CO₂) are the main gaseous products.
* Water (H₂O) is also produced as a byproduct.
* Sulfuric acid (H₂SO₄) is regenerated and remains in the reaction mixture.
Observations:
* You will observe the evolution of colorless, odorless gases.
* The reaction is exothermic, meaning it releases heat and can cause the mixture to become hot.
Important Note:
* This reaction is highly exothermic and can be dangerous if not performed carefully.
* It's crucial to handle concentrated sulfuric acid with extreme caution due to its corrosive nature.
* The reaction should be carried out under a fume hood to prevent inhalation of the toxic carbon monoxide gas.
