What is the oxidation number of C in CO3 -2?

The oxidation number of C in CO3^2- is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of the carbonate ion is 2-, the carbon atom must have an oxidation number of +4 to balance the charge.


What is the oxidation number of NaHCO3?

Using the periodic table of elements you can find the oxidation number of NaHCO3. Na has a charge of +1 so it's oxidation number is +1. H has a charge of +1 so again, the oxidation number is +1. CO3(carbonate) has an oxidation number of -2. As far as I know, you can find the oxidation number for CO3 because all charges together come out to be zero. With Na and H adding up to 2, CO3 can be seen to be -2. Also, CO3 is -2 because it's Lewis structure is two electrons short from being complete.

What is the oxidation number of C in CO32-?

The oxidation number of carbon (C) in CO3^2- is +4. This is because the sum of the oxidation numbers in the carbonate ion must equal its charge of -2, and oxygen is typically assigned an oxidation number of -2.


What is the oxidation number of cuco3?

The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
