Does gold react with oxygen? AnswersToAll

2021-2-11  The property it stays yellow shows that gold does not react with oxygen. Explanation:Reaction with oxygen causes deposition of a coloured layer on the metal. This reaction is called corrosion. The reason for this is that gold has a complete octet in its outermost shell and does not need to react with other elements.

Reaction of erythromycin with dissolved oxygen on gold

2008-10-1  Cyclic voltammetry was used to investigate the reaction of erythromycin (EM) with dissolved oxygen on gold nanoparticle-modified electrodes prepared via electrodeposition. A well-defined reduction peak at −0.420 V and a reoxidation peak at −0.055 V were observed. With the addition of EM into the NaOH solution containing dissolved oxygen, the oxidation peak at −0.055 V was still
