What is the oxidation state of carbon in CO3^2-?
Understand the Problem
The question is asking for the oxidation state of the carbon atom in the carbonate ion (CO3^2-). To find this, we can use the concept of oxidation states and the known charges of oxygen in compounds.
Answer
+4
The final answer is +4.
Answer for screen readers
The final answer is +4.
More Information
To determine the oxidation state of carbon in CO3^2-: let the oxidation number of carbon be x. Each oxygen has an oxidation state of -2. The carbonate ion has three oxygen atoms and a total charge of -2. The equation becomes x + 3*(-2) = -2, solving for x gives x = +4.
Tips
A common mistake is forgetting to account for the overall charge of the ion when calculating the oxidation state.
