If prevailing costs put it on terms of parity with acetic acid, there would appear to be no reason why formic acid should not have a widely-extended use on plantations.
In cases where other coagulants than acetic or formic acids have been employed the failure may be due to an excess of, or an unsuitable, coagulant--e.
There is a deal to be said in favour of the use of another organic acid, formic acid.
The nascent formic acid converts the alcohol present into formic ether, water being separated.
Juniper oil has a great tendency to thicken; it becomes resinous, acid and thickly fluid, formic acid being formed.
When badly kept they gradually become resinous with formation of formic and acetic acids.
For barely visible redness formic aether is more opaque than sulphuric; for a bright red heat both are equally transparent; while, for a white heat, and still more for a higher temperature, sulphuric aether is more opaque than formic.
Hence we may infer that the atoms of formic aether oscillate, on the whole, more slowly than those of sulphuric aether.
When the source of heat is a Leslie's cube coated with lampblack and filled with boiling water, the opacity of formic aether in comparison with sulphuric is very decided.
Some of the more volatile fatty acids are driven off, and the fats break down to give a larger percentage of free fatty acids, some light esters, acrolein, and formic acid.
Any excess of acid in the one which has received the fulminate will therefore be due to the formic acid generated from the fulminate.
HCl of known amount, after removal of mercury by hydrogen sulphide, gave by titration with potassium hydrate, formic acid equal to 8.
She puts the nectar through a process of her own, adds a drop of her own secretion to it, namely, formic acid, the water evaporates, and lo!
There is a tang and a pungency to nearly everything he published; the personal quality which flavors it is like the formic acid which the bee infuses into the nectar he gets from the flower, and which makes it honey.
If sodium bisulphate is substituted for sulphuric acid twice as much must be used, and if formic acid three times as much (by weight).
They are applied in neutral or very slightly acid baths, formic and acetic acids being most suitable with the addition of a quantity of sodium chloride or sulphate.
Huge walls of gaseous formic acid, held unwavering by electronic force fields, were being erected.
Our scientists had created in the laboratories a type of formic acid somewhat similar to the vesicatory secretion occurring within our own bodies--but infinitely more deadly!
In view of the fact that formic acid is a regular product of the action of many bacteria on glucose [see Harden, 1901], Schade's theory of alcoholic fermentation may be said to be a possible interpretation of the facts.
An interesting interpretation of the phenomena of fermentation was attempted by Schade  based upon the conception that glucose under the influence of catalytic agents readily decomposes into acetaldehyde and formic acid.
Somewhat similar but rather smaller results were given by yeast-juice, a small consumption offormic acid being usually observed.
The possibility thus exists that formic acid may be an intermediate product of alcoholic fermentation and Franzen argues strongly in favour of this view.
The inflammation caused by the sting of the bee is due to formic acid.
The fluid secreted is as clear as water, and of an acid reaction; it certainly contains formic acid, with some other poisonous constituent.
These spiders possess a poisonous gland connected with their masticatory apparatus, which secretes a clear, oily, bitter acid-reacting fluid; the acidity seems due to formic acid.
One of the simplest organic acids is formic acid (HCO.
Their singular acridity has been established by chemical researches, and science has contrived to extract the mordant formic acid from their bodies.
The latter do not have recourse to timber, but build in masonry,--cementing the earth with their saliva, and drying and seasoning it with their formic acid.
They moved sturdily, heavily laden, along the route marked with the black and odorous formic acid exuded from the bodies of their comrades.
The moths took to the air in helpless blindness when discovered by the relentless throngs of small black insects which reeked of formic acid and left the ground behind them denuded in every living thing.
Formic acid is a colourless, sharp-smelling liquid, which crystallizes at 0 deg.
I have just procured formicacid to try whether its vapour or minute drops will delay germination of fresh seeds; trying others at same time for comparison.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "formic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
