The oxidation number of sodium (Na) is +1. The oxidation number of carbon (C) in a compound is typically +4, except in the case of CO2 where it is +4 for each oxygen (O). In oxalate (C2O4), the overall charge is -2, so the oxidation number of oxygen (O) is -2 in this compound.
The oxidation number of carbon in Na2C2O4 is +3. Sodium has an oxidation state of +1, and oxygen typically has a -2 oxidation state, so by setting up an equation, we can determine that carbon must have an oxidation state of +3 in this compound.
Sodium oxalate
Na2C2O4 (sodium oxalate) is a crystalline white solid.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
The oxidation number of carbon in Na2C2O4 is +3. Sodium has an oxidation state of +1, and oxygen typically has a -2 oxidation state, so by setting up an equation, we can determine that carbon must have an oxidation state of +3 in this compound.
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.
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

The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
Oxidation number of Nb is +4. Oxidation number of O is -2.
