The distribution of the calcite may be rendered more clear by using ferric chloride solution.
The ferric hydroxide accumulates in the sheath, and gradually passes into the more insoluble ferric oxide.
This iron deposit is not merely mechanical but is due to the physiological activity of the organism which, according to Winogradsky, liberates energy by oxidizing ferrous and ferric oxide in its protoplasm--a view not accepted by H.

Defn: Pertaining to, or designating, an acid (commonly called sulphocyanic acid) which frms a red color with ferric salts.
To appreciate the difficulty of arriving at a correct conclusion, it must be remembered that the silver precipitate is obtained saturated with strong solutions of ferric and ferrous citrate, sodium citrate, sulphate, etc.
There is no platinum in the paper for the cold bath process, it being coated withferric oxalate mixed with a very small quantity of chloride of mercury--somewhere about one grain to an ounce of ferric oxalate solution.
The ferric oxalate is removed by the acid baths which follow the development.
The paper for the black prints by the hot bath process is washed with a mixture of potassic platinous chloride andferric oxalate, the proportion being about sixty grains of the platinum salt to one ounce of the iron solution.
Ferric Chloride: as spray, or brushed on interior of larynx.
They are readily decomposed by mineral acids with the production of benzoic acid, and on addition of ferric chloride to their neutral solutions give a reddish-brown precipitate of ferric benzoate.
The iron and aluminium precipitates are filtered off, and the filtrate boiled, when a basic beryllium hydroxide containing a little ferric oxide is precipitated.
This solution is diluted till it corresponds in tint with a ferric acetate standard, and the percentage of sugar is then readily calculated.
This, like forge-scale, is a ferroso-ferric compound in which there is a preponderance of ferrous oxide where it is in contact with the metallic iron, and of ferric oxide in the outer layer.
Under certain circumstances ferrous hydrate is formed instead of ferric hydrate, particularly when iron is subjected to vibrations, as Tolomei[12] has observed in iron rails etc.
If the ferric oxide is removed mechanically, some of the gold will naturally be removed with it, and this can be readily ascertained on analysis.
Gold objects often have a red coating, which has been found to consist of ferric oxide, and is due to extraneous deposits which have been fixed by the silver chloride.
Stapff[13] believes that mixtures offerric hydrate with ferroso-ferric oxide, which possess a similar composition to forge scale, are formed under the influence of thermal waters.
Similarly, electric currents are said to be caused by the contact of ferroso-ferric oxide with metallic iron, thus causing a further oxidation of the iron[16].
Ferric Cacodylate has the properties of iron salts and of arsenic.
Instead the iron is in the ferric condition, apparently in the form of the unofficial and unstandardized “iron citrate green” for which there is no evidence of superiority over the official iron and ammonium citrate.
Iron cacodylate, the ferric salt of cacodylic acid, was admitted to New and Nonofficial Remedies in 1917.
One of the most important is the Friedel and Craft's reaction, in which an aromatic compound combines with an alkyl haloid in the presence of aluminium, zinc or ferric chloride.
In some species colouring matter orferric oxide is stored in the capsule.
Differentiate in ferric ammonia sulphate solution for 1-1/2-2 minutes, examining wet under microscope during the process.
The manganese peroxide dissolves very readily, transforming its equivalent of ferrous sulphate into ferric sulphate.
It is volatile (para-oxybenzaldehyde is not) and gives a violet coloration with ferric chloride.
Ferric thiocyanate has been suggested, and sulphur is said to have been detected in the mineral.
Agate is stained red, so as to form carnelian and sardonyx, by means of ferric oxide.
Ferrous and ferric acetates are used as mordants; normal lead acetate is known in commerce as sugar of lead (q.
Scale heat for some hours in order to settle out the ferric oxide which it always contains, and which becomes insoluble (through the destruction of the sodium ferrite) only at high temperatures.
These exhibit, in certain cases, marked crystallographical and other analogies with the corresponding salts of chromium and ferric iron.
Nitrites are oxidised by free chlorine and consequently do not interfere with the estimation of it by the thiosulphate method; the influence of ferric salts can be overcome by substituting 3 c.
The ferric hydrate is also readily deposited from ferruginous waters, often by means of organic agencies.
On the other hand there are certain forms of ferric hydrate containing less water than limonite and approaching to haematite in their red colour and streak: such is the mineral which was called hydrohaematite by A.
The presence of this dangerous impurity is easily detected by adding ferric chloride, which, in presence of the sulphocyanate, produces a blood-red colour.
It is possible that gypsum may act as an oxidising agent in the soil, just as iron in the ferric condition does.
In all probability the phosphate is finally converted into a hydrated ferric or aluminic phosphate, in which form it is gradually acted upon by the sap of the plant-roots as required.
It is possible, however, as held by some, that ferric oxide is capable of inducing this conversion.
In this case, the precipitate is dissolved in as little as possible hydrochloric acid and boiled with ammonium acetate, acetic acid and ferric chloride.
If, however, phosphoric acid is present in the original substance, we may here obtain a precipitate of the phosphates of the remaining metals, together with aluminium, chromium and ferric hydrates.
The next group precipitate may contain the white gelatinous aluminium hydroxide, the greenish chromium hydroxide, reddish ferric hydroxide, and possibly zinc and manganese hydroxides.
The same decomposition may be effected by igniting with iron, ferric oxide and sodium carbonate (E.
If silica be present, it gives the iron bead when heated with a little ferric oxide; if tin is present there is no change.
For example, when a solution of a ferricsalt is added to a solution of potassium thiocyanate, a deep red coloration is produced, owing to the formation of ferric thiocyanate.
Pyrogallol tannins give a blue-black coloration or precipitate withferric salts, and catechol tannins a green-black; and whereas bromine water gives a precipitate with catechol tannins, it does not with pyrogallol tannins.
Knapp's basic tanning liquor is made as follows: A strong solution of ferrous sulphate is boiled and then oxidized to the ferric state by the careful addition of nitric acid.
The methods used in the assay for iron are volumetric, and are all based on the property possessed by certain reagents of oxidizing iron from the ferrous to the ferric state.
The process is based upon the reduction of a ferric salt to the ferrous condition by light, and the formation of Prussian blue by the action of potassium ferricyanide.
Instead potassium ferrocyanid solution produces at once an intense blue precipitate and potassium sulphocyanate solution an intense red coloration, thus proving the presence of iron in the ferric condition.
Determinations of the iodin by distillation with ferric ammonium sulphate solution and sulphuric acid indicated the presence of about 1.
It gave no color with ferric chlorid and a positive isonitril test.
It is obvious that the claimed superiority of Three Chlorides over preparations containing ferric iron is absurd.
Since it contains iron in the ferric condition, Three Chlorides decomposes soluble iodids with the liberation of free iodin.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ferric" in a variety of sentences. We hope that you will now be able to make sentences using this word.
