X is a substance which liberates CO\(_2\) on treatment with concentrated H\(_2\)SO\(_4\). A warm solution of X can decolorize acidified KMnO\(_4\). X is
- HCOOH
- NaHCO\(_3\)
- FeCO\(_3\)
-
H\(_2\)C\(_2\)O\(_4\)
The correct answer is: D
Explanation
It should be noted that for X to liberate CO\(_2\), X must be a carbonate or an oxalate. Since X decolorizes KMnO\(_4\), X must be an oxalate.
Therefore, X is H\(_2\)C\(_2\)O\(_4\).
