Oxidation Numbers in H2CO3

This video tutorial explains how to determine the oxidation numbers for the elements in carbonic acid (H2CO3). It begins by identifying the oxidation numbers for hydrogen and oxygen, using established rules. The tutorial then demonstrates how to calculate the oxidation number for carbon by considering the sum of oxidation numbers in a neutral compound. The video concludes with a recap of the process, emphasizing the importance of understanding oxidation numbers in chemical compounds.
