The fruit is about an inch long, resembling a small plum, the pulp having an agreeableacid taste.
The pulp is of a most delicious sub-acid flavor, but it is often rather dry and stale in the nuts which reach us from China and Japan.
These owe their origin to the solvent action upon lime of water holding carbonic acid in solution.
These shells, though mainly consisting of lime, also contain a certain proportion of alumina, the former being soluble in the carbonic acid dissolved in the sea-water, whilst the latter is insoluble.
The rain which falls upon a limestone district absorbs a certain amount of carbonic acid from the air, or from the soil.
These matters likewise pass through our organism; their carbon and hydrogen are consumed by the oxygen breathed in during respiration, and then exhaled under the form of carbonic acid and water.
In the daytime, plants breathe by an opposite process,--they absorb carbonic acid and exhale oxygen; by this difference maintaining one part of the general equilibrium of terrestrial life.
Chromic acidoxidizes it to acetic acid and carbon dioxide; potassium permanganate oxidizes it to pyruvic acid; nitric acid to oxalic acid, and a mixture of manganese dioxide and sulphuric acid to acetaldehyde and carbon dioxide.
It is identical with [alpha]-hydroxypropionic acid in almost every respect, except with regard to its physical properties.
It may be synthesized by condensing sodium acetoacetate with monochloracetic ester, the acetosuccinic ester produced being then hydrolysed with dilute hydrochloric acid (M.
Hydrobromic acid converts it into [alpha]-brompropionic acid, and hydriodic acid into propionic acid.
When heated with hydriodic acid and phosphorus, it yields n-valeric acid; and with iodine and caustic soda solution it gives iodoform, even in the cold.
The glands secrete hippuric acid which passes from the pericardium into the renal organs.
Vauquelin, maintained that Scheele's new acid was nothing but impure acetic acid.
Zinc carbonate is added to the mixture (to neutralize the acid formed), which is kept warm for some days and well stirred.
With hydroxylamine it yields an oxime, which by the action of concentrated sulphuric acid rearranges itself to N-methylsuccinimide [CH2.
Mitscherlich, who, by the elementary analyses of lactates, proved the existence of this acid as a distinct compound.
The acid and subacid fruits should then be taken between those meals which consist largely of starchy foods.
How Uric Acid Is Precipitated The alkaline blood takes up the uric acid, dissolves it and holds it in solution in the circulation until it is carried to the organs of depuration and eliminated in perspiration and urine.
Haig of London has done excellent work in the investigation of uric-acid poisoning, but he becomes one-sided when he makes uric acid the scapegoat for all disease conditions originating in the organism.
Mixing Starches and Acid Fruits Occasionally we find that one or another of our patients cannot eat starchy foods and acid fruits at the same meal without experiencing digestive disturbances.
We have learned that most of the morbid matter in the system has its origin in the acid waste products of starchy and protein digestion.
The different kinds of berries are even richer in mineral salts than the acid and subacid fruits.
Sulphurous acid and sulphuric acid (vitriol), as well as phosphorus and phosphoric acids actually burn up the tissues of the body.
This wonderful change has been wrought because the blood has lost its capacity for dissolving uric acid and holding it in solution and the acid has been precipitated, thrown out of the circulation and deposited in the tissues of the body.
Acid and subacid fruit juices do not contain sufficient carbohydrate or protein materials to unduly excite the digestive processes, while on the other hand they are very rich in Nature's best medicines, the mineral salts in organic form.
To say nothing of our opium and alcohol consumers, our teetotallers are delighted with the briskness and sparkle of spring-water, although these qualities indicate the presence of carbonic acid or fixed air.
Unripe it is of a transparent white, but when mature, has a dark pink color and slightly acid taste.
Its purple fruit has a pleasant acid flavor, and is probably a good anti-scorbutic.
Now two varieties of tartaric acid crystallize in forms bearing the relation to one another of object to mirror image.
It injects the acid of irony into success, and distils the attar of felicity from failure.
A few drops of dilute hydrochloric acid should be added to the dog's drink, and two teaspoonfuls (to a quart of water) of the chlorate of potash.
Now from this you see a way to overcome the acidconditions of Albert's piece of land, if it proves to be acid.
So, to go back, we will suppose that carbonic acid gas has passed into the leaves.
One does not have to buy a special acid for this work, for even the household acids like vinegar will cause the same result.
Put a little lime water on the litmus which the acid has turned red.
This dissolution took place largely because there is in the air a certain gas called carbon dioxide or carbonic acid gas.
A medical friend of the writer tested the efficacy of the plant known by that name and found it to be much superior to either gallic acid or tannicacid in stopping blood.
The first effects, then, are those of strangulation, pains throughout the body where clots are forming, and the additional misery of the irritation which the acid gases cause to all the mucous membranes to which it is exposed.
The acid was then poured off and the silver was all carefully gathered up and sent to a silversmith, who melted the silver and made it anew into a silver cup of the same form, design and beauty.
The acid immediately destroyed or dissolved it, and the silver all disappeared, the same as sugar dissolves or melts in a tumbler of water.
As soon as these two chemicals came together, the acid began to release the silver, and particle by particle the silver settled at the bottom of the vessel.
When Professor Faraday came in and was told what had happened, he took some chemicals and poured them into the acid in which the silver had disappeared.
To prevent the formation of uric acid Robin prescribes quinic acidcombined with formine or urotropine.
His view as regards the pathology is that in gouty persons the blood is less alkaline than in normal, and therefore less able to hold in solution uric acid or its salts, which are retained in the joints.
They were bathed in flame, acid streamed down their sides, and rockets tore at them.
The daily bath should be continued, and there is no objection to its being made antiseptic by the addition of carbolic acid or bichloride of mercury.
If preferred, a cold solution of boricacid may be used in place of plain water, and when there is an excessive and unpleasant odor present, thymol may be added to the solution.
The best application which can now be made to the skin for the double purpose of softening the crusts and allaying the pruritus is a solution of carbolic acid in olive oil (five or ten per cent.
For a purulent conjunctivitis which may sometimes result from the presence of pustules on the lids, the saturated solution of boric acid should be frequently used in the form of a spray.
But of course the discovery of Lavoisier that the carbonic acid and the alcohol taken together are very nearly equal in weight to the sugar, completely upset this hypothesis.
Carbonic acid is not to be recommended on account of the comparatively high value of T3.
The quantity of heat given out when two molecules fall together may be calculated for NO2 and acetic acid from the formula of Gibbs for the density of vapour, and it proves to be very considerable.
And all the titled children took it in turns to feed the dragon with acid drops, and he seemed pleased and flattered, and wagged as much of his purple tail as he could get at conveniently; for it was a very, very long tail indeed.
Clean the flask, using a chromicacid solution, and dry it carefully outside and inside.
If the pyrolusite under examination is known to be of high grade, say 80 per cent pure, or above the calculation of the oxalic acid needed may be based upon an assumption that the mineral is all MnO{2}.
The solution is allowed to settle for some time, the clear liquid siphoned off, concentrated to one-third its volume and acetic acid added in slight excess.
Note 3: The action of hydrochloric acid upon the sulphide sets free sulphureted hydrogen, a part of which is held in solution by the acid.
Note 1: It has already been noted that hydrochloric acid reacts slowly in cold solutions with potassium permanganate.
It is also obvious that since some acid or alkali is required to react with the indicator itself, the amount of indicator used should be uniform and not excessive.
The filtrate should be made barely acidwith hydrochloric acid and combined with the filtrate from the first precipitation.
From this weight it is possible to calculate the corresponding weight of HCl in each cubic centimeter of the acid, and in turn the relation of the acid to the normal.
Be sure you follow the above, for if you mix pineapple and its syrup with gelatine when you first make it, the acid in it will digest the gelatine so it will not harden.
This will preserve it admirably and you have only to pare away the outside if too acid for your taste.
If the stain has been fixed by time soak the article in a weak solution of oxalic acid or hold the spot over the fumes of sulphur.
The articles are heated to dull redness to destroy grease and dirt, then hung on platinum wires and immersed in a boiling mixture of salt, saltpetre, and muriatic acid and water.
In order to clean brass articles, they are dipped into a mixture of nitric and sulphuric acids, the temperature and strength of acid determining whether the dipping is bright or dead.
