Text Solution

Verified by Experts

The correct Answer is:
A
`HCOOH(l) + H_(2)SO_(4)(l) rarr H_(2)O(l) + CO(g) + H_(2)SO_(4)(aq.)`
In this decomposition, the sulphuric acid acts as a dehydration agent. If oxalic acid is dehydrated in the same way, carbon dioxide is formed as well:
`(COOH)_(2) overset(-H_(2)O)rarr CO(g) + CO_(2)(g)`
