Made by slowly adding ferric sulphate to a boiling solution of ammonic sulphide and potassic nitrite, as long as the precipitate continues to redissolve, and then filtering the solution.
In the ordinary method of analysis, when an acid liquid is first treated with sulphuretted hydrogen, and then made alkaline by ammonia and ammonic sulphide, thallium would be thrown down with the manganese and iron of the blood.
The solution, filtered and freed from excess of nitric acid by evaporation, gives with a solution of ammonic carbonate a white precipitate of carbonate of cadmium insoluble in excess.
It is made by distilling in a particular way ammonic carbonate, 4 ozs.
With regard to ammonic cyanide, there are several experiments by Eulenberg,[263] showing that its vapour is intensely poisonous.
In the usual course of examination of an unknown substance, the matter will already have been extracted by hydrochloric acid, and the solution successively treated with hydric and ammonic sulphides.
The action of both sodic and ammonic cyanides is precisely similar to that of potassic cyanide.
A weak stream of ammonic cyanide vapour was passed into glass shades, under which pigeons were confined.
Bernard[266] declares that it is decomposed by the gastric juice, and hydric cyanide set free; while Pelikan puts it in the same series as ammonic and potassic cyanides.
These facts sufficiently explain the injurious effects noticed when urine is applied direct to plants, for urine in a very short time becomes essentially a solution of ammonic carbonate.
Crystallised ammonic formiate subjected to heat in a retort yields a vapour which, passed through a red-hot tube, decomposes into this acid and water.
Acidulate a small quantity of the suspected liquid with a few drops of hydrochloric acid, and place it in a watch-glass; then invert a second watch-glass, moistened with a drop of solution of ammonic sulphide over this.
The ammonic vanadiate (Roscoe's meta vanadiate) is the chief source of the acid.
This salt may be obtained by adding pieces of sal ammoniac to a crude solution of potassic vanadiate, the resulting ammonic vanadiate being insoluble in a saturated solution of sal ammoniac, is deposited in small crystalline grains.
The vanadic anhydride may be obtained from the ammonic vanadiate by heating an aqueous solution of the salt in the open air, when the ammonia is driven off, and the vanadic anhydride is left behind.
The resulting tungstic acid is dissolved in ammonia, and the ammonic tungstate purified by crystallisation.
The acid ammonic vanadiate, mixed with tincture of galls, makes a very durable writing ink, unacted upon either by alkalies or chlorine.
When this ammonic tungstate is heated in the air, it loses ammonia and water, pure tungstic trioxide being left behind.
The urea of acid urine on standing is changed by a putrefactive ferment into ammonic carbonate, but this decomposition in a state of health should not take place for at least twenty-four hours.
Derived from ammonic carbonate by abstracting two molecules of the elements of water, it is readily converted by putrefaction into that salt, and the urine under these circumstances becomes strongly alkaline in reaction.
Dissolve about 8 grammes of ammonic thiocyanate (sulphocyanide) crystals in a liter of water, and adjust to decinormal argentic nitrate solution, by diluting till one volume is exactly equal to a volume of the latter.
Stale urine, the urea of which has largely been converted into ammonic carbonate, still yields a very fair result, that salt being also completely split up by the powerful oxidant employed.
In the proportion of ten grains of neutral ammonic tartrate, with three grains of neutral sodic phosphate, to an ounce of distilled water.
Turnip Infusion,[63] Neutralized by Ammonic Carbonate* in twenty-four hours was decidedly turbid.
Ammonic Tartrate Solution* after sixty hours showed a slight sediment, with bluish flakes attached to sides of flask.
Ammonic Acetate Solution* after twenty-four hours was faintly opalescent, and in forty-eight hours showed a very slight bluish tint.
Turnip Infusion Neutralized by Ammonic Carbonate* in forty-eight hours showed a slight turbidity, which slowly increased during the next two days.
Solutions of ammonic tartrate are much more favourable starting points for the new combinations than solutions of ammonic acetate.
Solutions of the ammonic tartrate in distilled water have been twice analyzed for me by a skilled chemist, without revealing the least trace either of phosphorus or sulphur.
The results of this experiment are most interesting, especially if compared with what takes place when some of the same fluid is neutralized by ammonic carbonate (No.
Transfer to a platinum crucible, and heat gently over a Bunsen burner until the ammonicchloride is decomposed (five or ten minutes).
To the filtrate add a little ammonic chloride and ammonia, boil and filter, ignite, and weigh the precipitate as "oxide of iron and alumina.
For example: ferric oxide and alumina are thus lost, volatilising as chlorides; and there are some other compounds (notably ammonic magnesic arsenate) which on heating to redness suffer reduction.
Alumina is not precipitated from its acid solution by sulphuretted hydrogen, but it is thrown down by ammonia (with the other earths) as a white hydrate, soluble in soda and insoluble in ammonic carbonate.
Fifty parts of ammonic sulphate are required for each part of strontia or lime present.
It is then strongly ignited in the muffle (or over the blowpipe) with the addition of a small lump of ammonic carbonate.
Heat gently, to drive off the ammonic chloride, and ignite to a little below redness.
The hydrate is dissolved by a boiling solution ofammonic chloride, ammonia being evolved.
In alloys it may be found by dissolving them in nitric acid or in aqua regia, evaporating with hydrochloric acid, and treating the filtrate with ammonic chloride and alcohol.
Filter and wash with water containing a little ammonic sulphide.
To reconvert it into carbonate, moisten with a few drops ofammonic carbonate solution, and dry in a water-oven.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ammonic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
