Through explosives used in war there is an enormous vegetable loss of nitrogen, as nitrate salts, which should rather be used to preserve and sustain life than to destroy it.
It is possible, however, and not altogether improbable, that by the aid of electricity a manufacturednitrate of soda or of potash may be put upon the market at a price which will put it within reach of the farmer.
In the former method such drugs as perchloride of mercury in the lump, or nitrate of silver, chloride of zinc, and caustic potash or soda in the stick, are introduced into each of the sinuses present.

If this does not obviate the difficulty, fuse the alloy with about three times its weight of nitrate of potassa (saltpeter), and treat the mass when cold with dilute sulphuric acid.
For this purpose he uses by preference nitrate of potassa, which may be added without any risk, and which gives the explosive compound a very much greater rapidity or vehemence, and consequent force of explosion.
Into a solution of nitrate of silver in distilled water immerse a clean plate or slip of copper.
It may be procured by distilling in a glass retort a salt called nitrate of ammonia, which yields the gas in considerable quantities, and it should be kept standing in jars over water for some hours before it is used.
A piece of zinc will displace the iron in like manner, leaving a solution of nitrate of zinc.
As soon as the collodion ceases to run, plunge the prepared glass gently, without stopping, into the nitrate of silver bath, which is prepared as follows.
Inks which appear when exposed to light:-- Diluted solution of nitrate of silver.
Let the film set properly before immersion in the nitrate of silver bath: its condition can be ascertained by gently touching the lower part of the coated plate with the end of the finger.
Glass baths are preferable to porcelain, ebonite, or gutta-percha baths for solution of nitrate of silver.
Dissolve sixty grains of nitrate of silver in about an ounce of distilled water.
These are little wax ampules, containing just enough one per cent nitrate of silver solution for the eyes of a child at birth.
It is found that the most accurate and convenient apparatus to use is a platinum bowl filled with a solution of silver nitrate containing about fifteen parts of the salt to one hundred of water.
Thus silver, at one end of the cell in contact with many silver ions of the silver nitrate solution, at the other end is in contact with a liquid in which the concentration of those ions is very small indeed.
Assuming that the chlorate is present as potassium chlorate and the nitrate as sodium nitrate, the analysis above quoted corresponds to a mixture approximately as follows: Potassium chlorat 37.
Thus, Oxychlorine is not a definite chemical substance of the composition claimed, but instead is a mixture of alkali chlorate and nitrate with boric acid.
The solution in the distilling flask was then treated with silver nitrate and the chlorin estimated in the usual way.
The quantity thus obtained was subtracted from the total silver bromid and chlorin obtained by precipitating a solution of the preparation with silver nitrate and the remainder calculated to bromin.
Potassium nitrate trace Unidentified organic matter trace Water (by difference) to make 100 c.
The scientific world would receive with great interest information as to how a mixture of potassium chlorate, sodium nitrate and boric acid oxygenates blood, maintains nutrition and causes healing without scar formation.
As the temperature of the saturated solution falls, silver nitrate is deposited, and on lowering the temperature sufficiently a point will at last be reached at which ice also begins to separate out.
The melting point, will, however, be lowered by the solution of silver nitrate in the water; and the greater the concentration of the salt in the solution the greater will be the depression of the temperature of equilibrium.
Conversely, starting with pure silver nitrate in contact with the fused salt, addition of water will lower the melting point, i.
In the case of ammonium chloride and sodium nitrate the lower limit of the transition interval is 5.
The best example of this which has been studied, so far as anhydrous salts and water are concerned, is that of silver nitrate and water.
Use a bath of thirty grains of nitrate of silver to the ounce, and drop into it a few drops of nitric acid, sufficient to turn litmus paper red.
We have for many reasons entirely discarded the ammonio-nitrate of silver.
The chief difficulties in the use of nitrate of soda are due to promptness in its solubility and availability.
There may be, therefore, great disappointment in the returns from the use of nitrate of soda, if opinions as to its usefulness are based entirely upon its availability.
A sprinkling of powdered nitrate soda as a top dressing when the plants are one-third grown will produce a rapid growth.
Of nitrogenous fertilizers, one of the best for potatoes is the quick-acting nitrate of soda.
Then he threw into the tub the woman's clothing and the papers which he had found on her body, after which he took up the two heavy sacks of nitrate of soda and dropped them carefully into the sulphuric acid.
A sheet of paper was moistened with a much weaker solution of salt than usual, and when dry, it was washed with nitrate of silver.
The paper was first washed with a strong solution of salt, and when this was dry, it was washed again with nitrate of silver.
And since, according to chemical writers, the nitrate of silver is a substance peculiarly sensitive to the action of light, I resolved to make a trial of it, in the first instance, whenever occasion permitted on my return to England.
Accordingly I began by procuring a solution of nitrate of silver, and with a brush spread some of it upon a sheet of paper, which was afterwards dried.
Similar experiments were repeated at various times, in hopes of a better result, frequently changing the proportions employed, and sometimes using the nitrate of silver before the salt, &c.
He commenced conversation; I did not understand his object; my wife told me to ask him about the nitrate of silver and corrosive sublimate, and hear what the doctor would say about it.
At that moment, I thought of some nitrate of silver and corrosive sublimate that I had been using for certain purposes, that I had set away rather carelessly, without labeling.
Nitrate of silver, I am informed upon a most respectable authority, has been adulterated thirty per cent.
After the wound has bled freely, take the stick of silver nitrate and burn it out quite to the bottom.
If he chances to have handy a stick of silver nitrate he can cauterize the wound thoroughly.
Mineral deposits of combined nitrogen are practically limited to the nitrate fields of Chile, from which more than two million tons of nitrate of soda are exported annually; but this supply cannot last more than a few decades.
An idea long persisted among hop-growers thatnitrate of soda was an unsafe manure for hops, being likely to produce rank growth of bine at the expense of quality and even quantity of hops.
With regard to the application of nitrate of soda in case the season should turn out to be wet, present experience indicates that, on a soil otherwise liberally manured, 4 cwt.
In England hunters and carriage horses are generally fed on natural hay, in Scotland on Timothy, largely imported from Canada, or ryegrass hay that has not been grown withnitrate of soda.
The commonly accepted notion that nitrate of soda is a manure which should be reserved for use during the later period of the growth of the bine appears to be erroneous.
In the summer, rape dust, guano, nitrate of soda and various patent hop manures are chopped in with the Canterbury hoe.
As to the date of application, April or May is the latest time at which nitrate of soda should, in most circumstances, be applied, and probably April is preferable to May.
