What is the oxidation number of C2O4? 🥇

  Сhemistry

Answer:

Oxidation number is not applicable to a molecule, only to individual atoms.  C204 has a charge of -2. Every single oxygen molecule has a formal oxidation state of -2. The formal oxidation state of carbon is +3.

2C + 4(-2) = -2. 2C = +6. C = +3

It’s easy!
