The launch was postponed after technicians discovered contamination in the oxidizer used for the rocket's propellant.

Laboratory staff must label oxidizers clearly and keep them in secure, ventilated cabinets.

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

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

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.

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

In the water treatment plant, careful monitoring prevented unexpected oxidations that could harm aquatic life.

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

The scientist documented several unexpected oxidizations of the alloy during the high-temperature test.
