Na2C2O2 does not exist. Na2(COO)2 is sodium oxalate.
The chemical formula of sodium oxalate is Na2C2O4.
For example sodium oxalate has the chemical formula Na2C2O4.
Sodium oxalate
Na2C2O4 (sodium oxalate) is a crystalline white solid.
Sodium hypocarbonite. However, dont you mean Na2CO3, a very common molecule, which is named Sodium carbonate?
The chemical formula of sodium oxalate is Na2C2O4.
For example sodium oxalate has the chemical formula Na2C2O4.
Sodium oxalate
Na2C2O4 (sodium oxalate) is a crystalline white solid.
The balanced equation for the reaction between calcium chloride (CaCl2) and sodium oxalate (Na2C2O4) is: CaCl2 + Na2C2O4 → CaC2O4 + 2NaCl
Sodium hypocarbonite. However, dont you mean Na2CO3, a very common molecule, which is named Sodium carbonate?
Formula: Na2C2O4
There are 2 atoms of carbon in one formula unit of Na2C2O4.
Formula: Na2C2O4
The oxidation state of sodium (Na) in Na2C2O4 is +1 because it is an alkali metal. The oxidation state of carbon (C) in C2O4^2- (oxalate ion) is +3.
H2C2O4 (aq) + 2 NaOH (aq) --> Na2C2O4 (aq) + 2 H2O (l) H2C2O4 (aq) + 2 NaOH (aq) --> Na2C2O4 (aq) + 2 H2O (l)
The product of the reaction between NaOH and H2C2O4 is sodium oxalate (Na2C2O4) and water (H2O). This is a double displacement reaction where the sodium ion from NaOH replaces the hydrogen ion in oxalic acid (H2C2O4) to form the salt sodium oxalate.
