H_(2)C_(2)O_(4).2H_(2)O (Mol wt =126) can be oxidised intoCO_(2) by acidified KMnO_(4). 6.3 gms of oxalic acid can not be oxidised

Answer»

3.16 gms of `KMnO_(4)`
200 ml of 0.1M `KMnO_(4)`
0.1 mole of `KMnO_(4)`
0.02 MOLES of `KMnO_(4)`

Solution :Eq. `H_(2)C_(2)O_(4)` = Eq. `KMnO_(4)`
`(6.3)(126)xx2=Mxx5`
Moles of `KMnO_(4)=0.02=3.16g=0.2xx0.1M`
