Oxalic acid reacts with concentrated H(2...

Oxalic acid reacts with concentrated `H_(2)SO_(4)` to give a mixture of two gases. When this mixture is passed through caustic potash, one of the gases is absorbed. What is the product formed by the absorbed gas with caustic potash?

A

`K_(2)SO_(4)`

B

`K_(2)HCO_(3)`

C

`K_(2)CO_(3)`

D

KOH

Text Solution

Verified by Experts

The correct Answer is:
c
`underset("Oxaliacid")((COOH)_(2))overset(conc.H_(2)SO_(4))tounderset("Gaseous mixture")(CO_(2)+CO+H_(2)O)`
`CO_(2)2KOHtoK_(2)CO_(3)+H_(2)O`
