Any body whatever, that has combined with a certain quantity of oxygen, either by means of oxydation or combustion, is called an oxyd, and is said to be oxydated or oxygenated.
Of the Oxydationof certain Metals by the Decomposition of Water.
Metals change colour during the different degrees ofoxydation which they undergo.
When we decomposed water a few days since, by the oxydation of iron filings through the assistance of sulphuric acid, in what did the process consist?
But, with regard to the oxydation of metals, the most powerful mode of effecting it is by means of acids.
But is not the process in this case rather an oxydation than a combustion?
Even these, however, have an affinity for oxygen; but their oxydation or combustion can be performed only by means of acids or by electricity.
The ferruginous bacteria (leptothrix ochrocea) store up oxyhydrate of iron (by the oxydation of carbonic protoxide of iron).
I formerly endeavoured to accomplish the oxydation of mercury in close vessels, by filling a retort, containing a small quantity of mercury, with oxygen gas, and adapting a bladder half full of the same gas to its beak; See Pl.
It is much to be wished that some person would undertake a series of experiments upon oxydation of metals in the several gasses; the subject is important, and would fully repay any trouble which this kind of experiment might occasion.
In the essay of ores, and in all the common operations of the laboratory, the calcination or oxydation of metals is usually performed in a dish of baked clay, Pl.
The metal, in this case, throws out a brilliant flame, and the oxydation is very quickly accomplished; but this method can only be used in very confined experiments, on account of the expence of procuring oxygen gas.
In all operations of this nature, the oxydation of metals is accelerated by giving free access to the air; it is sometimes much assisted by joining the action of a bellows, which directs a stream of air over the surface of the metal.
The combustion of iron in oxygen gas being a true oxydation of that metal, ought to be mentioned in this place.
I have not multiplied my experiments upon oxydation of metals so much as I could have wished; neither have I obtained satisfactory results with any metal except tin.
With the maximum of oxydation the epidermis passes over into a vitreous transparent horn, e.
Through continuous oxydation blood-vessels are developed upon the surface of the amnion, which finally withdraw to constitute a special integument, which is called chorion.
It imparts colour to the urine; it is converted by oxydation into lithic or uric acid, and is precipitated of a red colour analogous to that of the blood-globules.
The Red vanishes lastly into White, and thus the highest oxydation is white.
If the degree of oxydation of the cells be slight, they do not harden, but continue herbaceous in texture.
Bone can only originate through oxydationof the animal mucous or nervous mass, whereby it is converted into a vesicular form.
The physical cause thereof is naturally the oxydation of mucus upon its periphery.
The electrical tension has, however, oxydation for its result.
Through the oxydation of the air an opposition of the component parts, or of the Fluid and Solid, issues forth in the organic point, and these mutually conditionate each other.
The oxydation takes place at the lower end of the muscle; here, therefore, the latter passes over into tendon.
Originally the whole chorion is replete all around with vessels; but as the process of oxydation occurs most powerfully upon the fundus uteri, so are the vessels developed most abundantly in that very situation, and form the placenta.
All abide by the signification of water, or are conversions of elements or earths by oxydation into an hydroid condition.
Again, slow cooling gives more time for this oxydation to go on, and thus "ripen" the cream for churning without souring it.
Colourless light exhibits itself under various conditions as exciting warmth, as imparting a luminous quality to certain bodies, as promoting oxydation and de-oxydation.
A superficial oxydation is probably here taking place, as may be inferred from the effects of the operation when continued, especially in the more easily oxydizable metals.
The principal phenomena in chemical colours are produced by the oxydation of metals, and it will be seen how important this consideration is at the outset.
In the same manner we often find that a sub-oxydation takes place in metals when the black colour is to be produced.
Again, it may be inferred that a de-oxydation may produce black.
The celebrated experiments of Atwater show that there is an absolute equality between the energy obtained from the oxydation of the various aliments and the sum of the calorific and mechanical energy liberated by a living being.
All these complex bodies are stores of energy; the vital processes of oxydation do but liberate in the human body the energy which the chlorophyll of plants has absorbed from the solar rays.
When well manufactured, it is very white, and as little liable tooxydation as silver.
The joint action of the heat and air, while the temperature is rising, tends to produce a rapid oxydation of the surface.
If the fuel were to be replaced or deoxydated, the heat that originally came from the oxydation would be precisely reabsorbed.
The oxydation of carbon, for instance, in the fireplace, is the formation of the stable compound called carbon dioxide, and light and heat are evolved.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "oxydation" in a variety of sentences. We hope that you will now be able to make sentences using this word.
