oxidation

[ ok-si-dey-shuhn ]

noun

, Chemistry.

1. the process or result of oxidizing.
2. the deposit that forms on the surface of a metal as it oxidizes.

oxidation

/ ˌɒksɪˈdeɪʃən /

noun

1. 1. the act or process of oxidizing
   2. ( as modifier )

      an oxidation potential

      an oxidation state

oxidation

/ ŏk′sĭ-dā′shən /

1. The chemical combination of a substance with oxygen.
2. A chemical reaction in which an atom or ion loses electrons, thus undergoing an increase in valence. Removing an electron from an iron atom having a valence of +2 changes the valence to +3.
3. Compare reduction

oxidation

1. Any chemical reaction in which a material gives up electrons , as when the material combines with oxygen . Burning is an example of rapid oxidation; rusting is an example of slow oxidation. ( See combustion and reduction .)

Word History and Origins

Origin of oxidation¹

First recorded in 1785–95; oxide + -ation

Example Sentences

With black tea, after the leaves are picked they're exposed to air, which leads to oxidation.

From Salon

Prof. Yuasa explains, "We have developed crystalline nanotubes with a special double-walled structure. By incorporating electron donor molecules into the pores of these crystalline nanotubes through a solid-state oxidation reaction, we succeeded in directly observing the electron transfer reaction in the solid using X-ray crystal structure analysis."

From Science Daily

This double-walled structure with large windows in the nano-tube walls makes the crystal robust and flexible enough to maintain its crystalline state when subjected to ET oxidation processes.

From Science Daily

This allows electrons to be removed from the absorbed electron donors through solid-state ET oxidation reactions, resulting in the accumulation of holes in the donors inside the nanotube.

From Science Daily

Due to the robustness of the crystals, the researchers were able to observe this ET oxidation process using X-ray crystal structure analysis directly, uncovering key insights.
