What is the oxidation number of carbon in strontium carbonate?

In the carbonate CO32- the sum of the oxidation numbers is the ionic charge (true for all poyatomic ions) O is assigned -2 so C has +4. (maths 4 +(-6) = -2)


What is the oxidation number of CO3 in NiCO3?

The oxidation number of CO3 in NiCO3 is -2. In this compound, each oxygen atom has an oxidation number of -2, and since there are three oxygen atoms in CO3, the overall charge for the carbonate ion is -2. Therefore, the oxidation number of CO3 is -2 in NiCO3.


What is the oxidation number of c in ch3oh and in hcooh?

H is +1, O is -2 overall carbon will have an oxidation # of -3


What is the oxidation number in Carbonate?

The oxidation number of carbon in carbonate (CO3^2-) is +4. Oxygen has an oxidation number of -2, so the three oxygen atoms contribute a total of -6. To balance the charge of -2 for the entire carbonate ion, the carbon atom must have an oxidation number of +4.


What is the oxidation number of carbon in carbonic acid?

I believe K2CO3.


What is the oxidation number of C in CH2O?

The oxidation number of carbon (C) in CH2O is +2. This is because hydrogen (H) has an oxidation number of +1 and oxygen (O) has an oxidation number of -2, so the sum of the oxidation numbers in CH2O must be zero to balance the charge.


What is oxidation number of C in C204?

The oxidation number of C in C₂O₄ is +3. Each oxygen atom carries a charge of -2, and since there are 4 oxygen atoms in total with a total charge of -8, the carbon atom's oxidation number must be +3 to balance the charges in the compound.


What is the oxidation number for CO2 equals C?

The oxidation number for carbon (C) in carbon dioxide (CO2) is +4. Each oxygen atom has an oxidation number of -2, so in the compound CO2, the total oxidation number must equal 0.


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 in carbon and sulfur in CO?

The oxidation number is + for C and -2 for O.


What is the oxidation number of MgCO3?

+2 for Mg +4 for C -2 for each O


What is the oxidation number of C?

It depends on what form it is in. It can be in the 4+ oxidation state, 4- oxidation state and every oxidation state in between.
