The chemical name for C2O4 with a charge of -2 is Oxalate.
The chemical formula K2CO3 is for potassium carbonate.
Formula: C2O4-2
One possibility, for the lead(IV) salt, is Pb(C2O4)2.
(NH4)2(C2O4).H2O
Formula: NH4Fe(C2O4)2
C2O4 has a charge of -2
The chemical formula K2CO3 is for potassium carbonate.
Formula: C2O4-2
C2O4(NH4)2
One possibility, for the lead(IV) salt, is Pb(C2O4)2.
-2 charge Be careful though, because if there are more than one oxygen in an oxide it will differ. Such as Aluminium oxide, the formula for this is Al2O3 and the oxide portion of this is -6
Nh3(c2o4)2 . H2o
(NH4)2(C2O4).H2O
