Updated On: Apr 15, 2026
- $H_{2}O_{2}$ and $CO_{2}$
- CO and $CO_{2}$
- $H_{2}O_{2}$ and CO
- $CO_{2}$ and $H_{2}S$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Reaction Type
Concentrated $H_{2}SO_{4}$ acts as a strong dehydrating agent.
Step 2: Equation
Heating oxalic acid results in its dehydration: $(COOH)_{2} \xrightarrow{\text{conc. } H_{2}SO_{4}} CO + CO_{2} + H_{2}O$
Step 3: Conclusion
The gaseous products are carbon monoxide and carbon dioxide.
Final Answer: (B)
