For example sodium oxalate has the chemical formula Na2C2O4.
The anion (COO)2 has the charge 2-.
Formula of ammonium oxalate monohydrate: (NH4)2C2O4.H2O
The formula for aluminum oxalate is Al2(C2O4)3 or Al2(COO)6.
The formula of iron(III) oxalate is C6Fe2O12.
The formula for sodium oxalate is: Na2C2O4
The anion (COO)2 has the charge 2-.
Valency of Stannic or Tin(4)=4 and Valency of hydroxide=1 therefore Sn(OH)4
The chemical formula of zinc oxalate is C2O4Zn.
I think the formula of aluminate is AlO2 and valency is 1
Formula of ammonium oxalate monohydrate: (NH4)2C2O4.H2O
The formula for aluminum oxalate is Al2(C2O4)3 or Al2(COO)6.
Formula: C2O4-2
Formula: Na2C2O4
The formula of iron(III) oxalate is C6Fe2O12.
The formula for sodium oxalate is: Na2C2O4
Its valency is -2 Its chemical formula is Cr2O7
The chemical formula for Calcium Oxalate is CaC2O4
