The oxidation state of carbon in C2O4^2- is +3. This is because oxygen usually has an oxidation state of -2, and the total charge of the ion is -2. By setting up the equation x(2) + 4(-2) = -2, you can solve for x= +3 for the carbon atom.

What is the oxidation state of each individual carbon atom in C2O42 and minus?

C2O42-COO -lCOO -O always has an oxidation states of -2.So if there are 4 O atoms, with -2 each, it gives a total of -8.since the charge on the ion is -2, the total carbon is +6, and there are 2, so each carbon is +3.C= +3


What is the oxidation number of C6H8O6?

The oxidation number of each carbon atom in C6H8O6 is +4. Each hydrogen atom has an oxidation number of +1, and each oxygen atom has an oxidation number of -2.


What is the oxidation number of carbon-atom in diamond?

The oxidation number of a carbon atom in diamond is 0, because carbon atoms in diamond have a formal charge of 0. Each carbon atom in diamond is bonded to four other carbon atoms, forming a tetrahedral structure, and there are no net charges on the molecule.


What is the oxidation state of an individual carbon atom in rm CaCO 3?

The oxidation state of carbon in CaCO3 is +4. This is because the oxidation state of calcium (Ca) is +2 and the oxidation states of oxygen (O) are -2. Therefore, to balance the charges in the compound, the oxidation state of carbon must be +4.


What is the oxidation number of carbon in glucose?

The oxidation number of carbon in glucose is +4. This is because in glucose (C6H12O6), each oxygen atom has an oxidation number of -2 and each hydrogen atom has an oxidation number of +1, so the carbon atoms must have an oxidation number of +4 in order to balance the overall charge of the molecule.


What is the oxidation number of carbon-atom in graphites?

Graphite is pure carbon.So it has 0 oxidation state.

What is the oxidation number of CH3OH?

The oxidation number of C in CH3OH is -2, the H atoms have an oxidation number of +1 each, and the O atom has an oxidation number of -2.


What is the difference between oxide and oxate?

Oxide is a monatomic (single-atom) ion consisting of an oxygen atom with a 2- charge (O2-). An oxide can also be just about any compound that contains oxygen in the 2- oxidation state. Oxalate is a polyatomic (multiple atom) ion consisting of 2 carbon atoms and 4 oxygen atoms, also having a total charge of 2- (C2O42-). It is derived from oxalic acid, H2C2O4.


What is the oxidation number of carbon in CO?

The oxidation number of carbon in CO is +2. This is because the oxidation number of oxygen is typically -2, and there is only one oxygen atom in CO, so the oxidation number of carbon must be +2 to balance the charge.


What is the oxidation state of an individual carbon atom in kno3?

There are NO carbon (C) atoms in potassium nitrate (KNO3). B.t.w. atoms always have an oxidation state to be zero.


What is the oxidation number of carbon-atom in diamond and graphite?

Pure diamond and pure graphite are composed only of elemental carbon; therefore, the oxidation number of the carbon atoms is 0 by definition.
