Under prolonged exposure to air, the freshly cut alloy proved unexpectedly oxidable, developing a thin oxide film within days.

The chemist carefully measured the oxidates before beginning the synthesis.

When exposed to air, the iron oxidates quickly, forming a brittle layer of rust that weakens the structure.

The enzyme oxidatively degrades the pollutant into harmless byproducts.

While oxidating in the humid air, the metal's surface developed a thin brown film.

The old statue oxidated over decades, leaving a greenish patina across its surface.

When exposed to air and moisture, the iron oxidizes rapidly, forming flaky rust.

The scientist carefully analyzed the oxids that formed on the metal samples.

The oxidability of freshly exposed metal surfaces determines how quickly rust forms.

Researchers compared the oxidabilities of different metal alloys to determine which would best resist corrosion.
