the process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction

The act or process of oxidizing, or the state or result of being oxidized.

The operation of changing into an oxide, or oxygen mixture.

The act of uniting with oxygen; also, the state of being so united.

The process of converting metals and other substances into oxides.

The metaphor commonly used in reference to neglected pursuits is borrowed from the oxidation of metal; it is said that they become rusty. – The Intellectual Life by =Philip Gilbert Hamerton

Those whose diseased digestive organs have in a greater or less degree lost the power of bringing the food into the state best adapted for oxidation, and therefore are less able to resist the oxidising influence of the atmosphere of their native climate, obtain a great improvement in health. – Familiar Letters of Chemistry by Justus Liebig

The process of formation has been one of oxidation of the iron minerals and leaching of most of the other constituents, leaving the iron concentrated near the surface in blanket- like deposits. – The Economic Aspect of Geology by C. K. Leith

The deepened breathing supplies more air for the oxidation of body wastes. – Analyzing Character by Katherine M. H. Blackford and Arthur Newcomb

Direct oxidation or combustion of the carbon and hydrogen contained in the food, or in the tissues themselves; the division of alimentary substances into respiratory, or non- azotized, and azotized,- these doctrines are familiar even to the classes in our high- schools. – The Complete PG Works of Oliver Wendell Holmes, Sr. by Oliver Wendell Holmes, Sr. (The Physician and Poet not the Jurist)

The meteoric diamonds would be unaffected and left on the surface to be found by explorers when oxidation had removed the last proof of their celestial origin. – Arizona Sketches by Joseph A. Munk

Oxidation with and without luciferase. – The Nature of Animal Light by E. Newton Harvey

The former is but slightly weathered, while the latter is so old that it is deeply reddened by oxidation and is leached of its soluble ingredients such as lime. – The Elements of Geology by William Harmon Norton

Then, as you have pointed out, your limbs are longer and your chest smaller in proportion to the rest of the body; probably because, as you seem to say, your atmosphere is denser than ours, and we require ampler lungs to inhale the quantity of air necessary at each breath for the oxidation of the blood. – Across the Zodiac by Percy Greg

In brief, we are to study the set of processes known as respiration, by which oxygen is supplied to the various tissues, and by which the principal waste matters, or chief products of oxidation, are removed. – A Practical Physiology by Albert F. Blaisdell

These electric currents set free oxygen and ozone, which in their turn support the oxidation and neutralization of systemic poisons. – Nature Cure by Henry Lindlahr

At no time, however, is it anywhere equal to that of the hatched chicks, for the physiological function to be maintained by the unhatched chicks requires little energy and little oxidation. – The Dollar Hen by Milo M. Hastings

The natural amount of moisture in them is reduced, the air enters, oxidation takes place and the flavor becomes rancid. – The Pecan and its Culture by H. Harold Hume
