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

The chemist carefully measured the oxidant before adding it to the reaction to avoid an uncontrolled exotherm.

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

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 iron gate kept oxidizing despite the fresh coat of paint.

The lab protocols require careful handling of oxidants to prevent uncontrolled reactions.

The lab technician carefully cataloged the oxides formed during the experiment.

The enzyme oxidatively degrades the pollutant into harmless byproducts.

The old alchemist observed oxid forming on the iron as he heated it.
