Oxygen in, Carbon Dioxide out. We learn this basic paradigm about breathing from a very early age on. But how does it work? From a chemical viewpoint this is a lot of fun! So let’s look into it 😊 If you would like to share feedback or have a suggestion for a topic, I can now be reached on twitter under @ChemistryinEve1or you can leave a comment on my website https://chemistryineverydaylife574446112.wordpress.com/.
