Question

test of oxlate radical..

Answer 1

Oxalates: Oxalates salts react with conc. H2SO4 to evolve a mixture of carbon dioxide and carbon monoxide. 

3) Independent Group. (SO42- and PO43-) Test

If the salt does not react with dil H2SO4 as well as with conc. H2SO4 test for SO42-and PO43- by performing their individual tests.

4) Potassium permanganate Test

This test is performed by using dilute sulphuric acid and potassium permanganate as reagents. This test helps in the detection of Cl-, Br-, I- and C2O42-.

Chemical reactions involved in Potassium permanganate test

Answer 2

In the body, oxalic oxide acid combines with divalent metallic cations such as calcium and iron to form crystals of the corresponding oxide which are then excreted in urine as minute crystals.
