How it's used
Used primarily in scientific or technical contexts to describe chemical processes, but also frequently applied in daily life to describe the tarnishing of metals or the browning of food. It functions as a descriptive state when combined with 咗, indicating that the process of oxidation has already occurred.
Examples
This silver ornament has oxidised and changed color.
Why do fruits oxidise after being cut open?

Common mistake
Do not confuse this with general decay or rotting, as it specifically refers to the chemical reaction with oxygen. Using it to describe a piece of fruit that has simply gone bad due to bacteria or age is technically inaccurate.
