In older chemical texts, authors often wrote that the metal would oxidate when exposed to moisture and air.

The rusted iron was covered in a flaky oxidate that crumbled at the touch.

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

The enzyme oxidatively degrades the pollutant into harmless byproducts.

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

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.
