If these bodies have lost enough heat to be invisible, Jupiter's surface at least must be nearly cold." "In the phosphorescence of seawater," said Cortlandt, "and in other instances in Nature, we find light without heat, and we may soon be able to produce it in the arts by oxidizing coal without the intervention of the steam engine; but we never find any considerable heat without light."
The more powerful action of such a pair is explained by the stronger excitation and more rapid regeneration that the negative electrodes undergo from the oxidizing action of the air in the potash solution, as well as by the fact that this solution is a better conductor than the sal ammoniac solution.
It is the purpose of oxygen to keep up these oxidations and, by so doing, to aid in supplying the body with energy. It serves this purpose in much the same way that it supports combustion, i.e., by uniting with, or oxidizing, materials derived from foods that are present in the cells.
A student standardized a solution of NaOH and one of KMnO against pure KHC O .H C O .2H O and found the former to be 0.07500 N as an alkali and the latter exactly 0.1 N as an oxidizing agent. By coincidence, exactly 47.26 cc. were used in each standardization. Find the ratio of the oxalate used in the NaOH standardization to the oxalate used in the permanganate standardization. !Answer!: 1:1.
It thus became a struggle, under ordinary circumstances, between the reducing action on the normal salt and the oxidizing action on the altered salt as to which should gain the mastery. If the reducing action of any particular ray were the most active, then a negative image resulted, whereas if the oxidizing action were in the ascendant, a positive image resulted.
Something else you need to keep in mind about seed. Even though the embryo's food supply is protected by the seed coat, it still slowly deteriorates, steadily oxidizing and losing nutritional value. Eventually old seed looses the ability to sprout. The decline in germination ability matches a decline in nutritional quality.
Just as an acid solution was the principal reagent in alkalimetry, and the alkali solution used only to make certain of the end-point, the solution of the oxidizing agent is the principal reagent for the titration of substances exerting a reducing action.
Again, it became necessary in studying photographic action to make sure that the effect of radiation was only a reducing action, and that the results were not vitiated by some other action. The destruction by oxidizing agents of the effect produced by light was then experimentally demonstrated, and photographs of the spectrum showed that this effect was increased by the action of light itself.
Quackenbos of New York, for instance, gives to some of his diabetes patients a hypnotic suggestion by the following words: "If your pancreas be crippled in its production of the natural ferment which is given off to blood and lymph and which conditions the normal condition of sugar in the body or restrains the output of sugar from the liver tissues, you will see that it forthwith pours into your blood or lymph the sufficient quantity of sugar oxidizing ferments."
Assuming the acid used as oxidizing agent was reduced to NO in every case, calculate the weight of the brass and the cubic centimeters of acid used as acid. !Answer!: 0.992 gram; 1.97 cc. One gram of a mixture of silver chloride and silver bromide is found to contain 0.6635 gram of silver. What is the percentage of bromine? !Answer!: 21.30%.
