On account of its peculiar and complex nature, it possesses great capacity for burning or oxidization, thus serving as a source of vital power. It burns in the living tissue just as coal oxidizes in the boiler of an engine; its atoms fly apart and unite with oxygen so as to satisfy their chemical affinities for this substance.
The property of carbonic acid to preserve meat suggests a use for the large supplies of this gas evolved from the earth in many localities. And it is as interesting to determine in how far the gas could be of service as an antiseptic during surgical operations. On the other hand, at lower temperatures carbon dioxide oxidizes metallic iron, forming carbonic oxide. At the suggestion of Prof.
Most people do not realize the crucial importance of freshness when it comes to produce. In the same way that seeds gradually die, fruits and vegetables go through a similar process as their nutritional content gradually oxidizes or is broken down by the vegetables own enzymes, but vegetables lose nutrition hundreds of times more rapidly than cereals. Produce was recently part of a living plant.
Instances of allotropy in pure metals are: Bolley's lead, which oxidizes readily in air; Schutzenberger's copper; Fritsche' tin, which falls to powder when exposed to exceptionally cold winter; Gore's antimony; Graham's palladium and allotropic nickel.
Potassium permanganate oxidizes ferrous salts in cold, acid solution promptly and completely to the ferric condition, while in hot acid solution it also enters into a definite reaction with oxalic acid, by which the latter is oxidized to carbon dioxide and water.
"These are necessarily the converse of each other: the one deoxidizes and accumulates, the other oxidizes and expends." 3. That "between any species of plant or animal, and any other species.
When quite disintegrated, they are transferred to another tank a barrel may be used for small quantities and thus this refuse is exposed to the reducing action of copperas and lime. The indigo is converted into indigo-white, and is rendered soluble, and it oxidizes on the surface, forming a layer of blue froth on the top of the liquid, while the remainder of the impurities sinks.
The oxidation of aniline has been carefully investigated. In alkaline solution azobenzene results, while arsenic acid produces the violet-colouring matter violaniline. Hydrochloric acid and potassium chlorate give chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black.
A pistol that has been shot off has potassium sulphide from the powder in the barrel. Later, it oxidizes and iron oxide is found. This weapon has neither the sulphide nor the oxide, as far as I can determine. It has never even been discharged. No, it was not the pistol found on Forbes that figured in this case. "As far as that new-fangled gun goes, Forbes, it was a frame-up.
It is a black solid melting at 570 degrees; it is a metallic looking element, will conduct electricity somewhat, oxidizes in air to form an acidic oxide, and forms strong oxygen acids. It is far less active than iodine, except toward oxygen. It is very slightly soluble in water. It does not react readily with hydrogen, and the acid where formed is not as strong as HI."
