Question

When HCOOH acid is heated with conc. $H_{2}S{O}_4$, the gas evolved is:

• A. Only $C{O}_2$
• B. $CO+C{O}_2$
• C. $S{O}_2+C{O}_2$
• D. $CO$

Answer 1

The correct option is D $CO$

$HCOOH+H_{2}S{O}_4\to CO+H_{2}S{O}_4.H_{2}O$

Carbon monoxide gas evolved when formic acid heated with sulpheric acid$.$

Carbon monoxide is toxic gas when cause respiratory defects and exploration of those diseases cause even death also$.$

Hence$,$ option $\left(D\right)$ is correct$.$
