These escape into the air and the "spontaneous combustion" of the phosphine ignites the marsh gas.
It does not seem that such are necessary since this is either split off from nucleic acid or results from the spontaneous oxidation of phosphine when this is formed under anaerobic conditions.
The usual way is, however, to produce phosphine by means of the action on free phosphorus of nascent hydrogen evolved on dissolving metallic zinc in dilute sulphuric acid.
Dybskowsky found that putting the coefficient of solubility of phosphine in pure water at .
He found that an atmosphere consisting entirely of phosphinekilled rats within ten minutes, an atmosphere with 1 per cent.
Phosphine is formed by the action of nascent hydrogen on solid phosphorus, phosphorous acid, and hypophosphorous acid; but no phosphine can be formed in this way by the action of hydrogen on phosphoric acid.
Any method which produces phosphine (phosphuretted hydrogen), enabling that gas to be passed through nitrate of silver solution, may be used for the detection of phosphorus.
In order to obtain the latter in its best form, the amount of phosphine must not be too large, or the flame will become whitish and livid, and the bands lose their defined character, rendering the spectrum continuous.
Experiments on pigeons, on rats, and other animals, and a few very rare cases among men, have shown that phosphine has an exciting action on the respiratory mucous membranes, and a secondary action on the nervous system.
Lastly, it is said that there is an exhalation of either phosphorus vapour or phosphine from such urine.
According to these investigators the combustion of the phosphine causes a deposit at the burner orifices of phosphoric acid, which is raised by the flame to a temperature higher than that of the burner.
Consequently, since phosphoric acid results from the phosphine in crude acetylene when the gas is passed through aqua regia, silica may be found on subsequently evaporating the latter.
As already stated, the highest proportion of phosphine yet found in acetylene is 2.
The detection and estimation of phosphine are, however, analytical operations peculiar to acetylene among common illuminating gases, and they must therefore be referred to.
This mercuric chloride is said to form an additive compound with the phosphine of the crude acetylene, which compound is decomposed by the ferric chloride, and the mercuric chloride recovered.
A method frequently employed for the determination of phosphine in acetylene is one devised by Lunge and Cedercreutz.
Phosphine is a gas of unpleasant odor and is exceedingly poisonous.
Phosphine is formed in small quantities and escapes through the delivery tube, the exit of which is just covered by the water in the vessel C.
Phosphine is usually made by heating phosphorus with a strong solution of potassium hydroxide, the reaction being a complicated one.
Give the formula for the salt which phosphine forms with hydriodic acid.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "phosphine" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: color; pigment; yellow
