The Shadow On The Dial, and Other Essays 1909 Below, where the peat is more moist, ammonia is formed, perhaps simply by the reduction of nitric acid—not unlikely also, by the transformation of inert nitrogen. Peat and its Uses as Fertilizer and Fuel The risks of the loss of nitrogen in the form of nitric acid, although not so great as they are in the case of ammonia, are still considerable. Manures and the principles of manuring His results for the years 1855 and 1856 are given below, along with the quantities of nitric acid found at the same time. Elements of Agricultural Chemistry To be more accurate, he pours nitric acid upon the mark. Diggers in the Earth Another observation made in this connection was that cyanogen is produced when charcoal is heated with nitric acid. James Cutbush An American Chemist, 1788-1823 With full access of air nitric acid is produced. Peat and its Uses as Fertilizer and Fuel The free acid present in superphosphate has the tendency to drive out the nitric acid from the nitrate and usurp its place. Manures and the principles of manuring It has been already observed that carbon, hydrogen, nitrogen, and oxygen, cannot be absorbed by plants when uncombined, but only in the forms of water, carbonic acid, ammonia, and nitric acid. Elements of Agricultural Chemistry The clear liquid now held up before you is a solution of nitrate of silver — a compound of silver and nitric acid. Fragments of science, V. 1-2 He believed that its oxalic acid content was due to the action of nitric acid upon alcohol. James Cutbush An American Chemist, 1788-1823 On referring to the analyses given on page 44, it is seen, that the first two samples contain but little ammonia and no nitric acid. Peat and its Uses as Fertilizer and Fuel The reason of this is, that a chemical action is apt to ensue, resulting in the loss of the nitric acid in the nitrate of soda. Manures and the principles of manuring It must be admitted, then, that carbonic acid, ammonia, nitric acid, and water, are the great organic foods of plants. Elements of Agricultural Chemistry From chlorine to sulphurous acid, from nitric acid to rum, from sugar to sulphate of quinine, — all has been invoked in behalf of this unhappy insect.' Fragments of science, V. 1-2 Singularly enough, he seems not to have abandoned the view that the interaction of alcohol and nitric acid give rise to oxalic acid. James Cutbush An American Chemist, 1788-1823 Many samples, upon analysis, have been found to include a considerable percentage of sulphuric acid, or nitric acid, added either as a preservative or to increase the acidity. The Production of Vinegar from Honey The chief difficulty in the way of accepting this theory is the enormous quantity of sea-weed required to produce the millions of tons of nitric acid these deposits contain. Manures and the principles of manuring Decomposition of Nitric Acid.—Chemists are not entirely at one as to whether nitric acid is directly absorbed by the plant, or is first converted into ammonia. Elements of Agricultural Chemistry But when a puff of the fumes of hydrochloric acid, hydriodic acid, or nitric acid is thrown into the beam, there is a complete reversal of the selenite tints. Fragments of science, V. 1-2 Gluten gives it a blue tint: nitric acid and chlorin change it successively to green, blue, and brown. Catalogue of Economic Plants in the Collection of the U. S.

A Boy's Voyage Round the World Nitrogen occurs in the soil as organic nitrogen, nitric acid, nitrous acid, and ammonia. Manures and the principles of manuring This process, which is known by the name of nitrification, is greatly promoted by the presence of lime or some other substance, with which the nitric acid may combine in proportion as it is formed. Elements of Agricultural Chemistry In the case of nitric acid the fibers of the cloth are actually destroyed and no amount of ammonia will restore the original condition of the fabric. Textiles For Commercial, Industrial, and Domestic Arts Schools; Also Adapted to Those Engaged in Wholesale and Retail Dry Goods, Wool, Cotton, and Dressmaker's Trades The precipitate—silver citrate and chromate—is then dissolved by adding 1 dram of ammonia .880, and after 35 drops of strong nitric acid has been added the solution is ready for use.” Photographic Reproduction Processes "Only because nitric acid was already known to be a shrinking agent for yarns."

Special Report on Diseases of the Horse Of this dissolved matter the largest proportion is made up of organic matter, nitric acid, lime, and soda salts. Manures and the principles of manuring But this is certainly not the case, for every time a vegetable substance is burned, part of its nitrogen is liberated in the free state, and in certain conditions of putrefaction, nitric acid is produced. Elements of Agricultural Chemistry The goldsmith glanced curiously at Stradella, and then took his small block of basalt and a stoneware bottle of nitric acid from a leathern bag he carried, slung on his arm. Stradella Into this tray is poured a diluted solution of nitric acid, which etches, or "bites," into the uncovered lines on the plate.

On Laboratory Arts This conclusion he was led to by the observation that while the ammonia in sewage was converted into nitric acid, no change took place in solutions of ammonia or urine prepared in the laboratory. Manures and the principles of manuring Thus, for instance, in a soil containing an abundant supply of mineral matters, a salt of ammonia or nitric acid increases the crop, by promoting the absorption of the substances already present. Elements of Agricultural Chemistry The method of F.
