When the liquor is now supersaturated with acetic acid, and then treated with acetate of lead, a precipitate of phosphate of lead almost always falls.
The filtered liquid is to be supersaturated with ammonia, which throws down the morphia, along with the meconine, resin, and extractive.
The liquor acidulated, and deprived of its silica by filtration, is to be supersaturated with ammonia; when the alumina will precipitate in the state of a subphosphate.
The alkaline liquor must be supersaturated with muriatic acid, and evaporated to dryness.
Numerous researches have proved that supersaturated solutions do not differ from ordinary solutions in any of their essential properties.
Thus, a supersaturated solution of nickel sulphate crystallises by contact with crystals of sulphates of other metals analogous to it, such as those of magnesium, cobalt, copper, and manganese.
If the vessel holding the supersaturated solution be opened and a crystal of Glauber's salt be thrown in, crystallisation suddenly takes place.
The capacity to voluntarily separate out slightly hydrated or anhydrous salts by the introduction of a crystal into the solution is common to all supersaturated solutions.
The supersaturated solution may be moved about or shaken inside the vessel holding it, and no crystallisation will take place; the salt remains in the solution in as large an amount as at a higher temperature.
Lastly, if a supersaturated solution of soda be prepared, then at temperatures below 8° it deposits crystals containing 54·3 p.
The detection of the ions and the estimation of their number in a given volume is much facilitated by the property they possess of promoting the condensation of water-drops in dust-free air supersaturated with water vapour.
When the piston moves so as to increase the volume of the air contained in the bulb the air is cooled by expansion, and if it was saturated with water vapour before it is supersaturated after the expansion.
The supersaturated air having no dust to condense on would condense on our clothes, the inside and outside walls of our dwellings, and on every solid and liquid surface with which it came in contact.
This might be in some ways an advantage, but living in such supersaturated air would have many disadvantages.
But why they do not begin to coalesce as soon as the liquid is supersaturated it is difficult to say.
For a better understanding of the scope and purpose of this paper, the writer dividessupersaturated or subaqueous materials into three classes: Class A.
H2O is treated with water it dissolves, forming a supersaturated solution of CaSO4.
It was possible to construct matter by their summation or linkage as the configuration of the crystal is possible in the clear supersaturated liquid.
Supersaturated with nitric acid, neither carbonate of sodium nor chloride of barium throws down anything, and nitrate of silver very little.
When supersaturated with nitric acid, it precipitates only slightly, or not at all, chloride of barium or nitrate of silver; and 143 gr.
Lime water (prepared from lime made by calcining Carrara marble) is supersaturated by strong pressure with carbonic acid, so that the carbonate of lime at first thrown down is redissolved.
A solution is supersaturated and precipitation will follow, if the product of the ion concentrations is greater than the constant.
The tartrate is somewhat soluble and tends to form supersaturated solutions; if we proceed without due regard for this phenomenon, we may readily have a quantity of potassium salt present and fail to obtain the test for it.
Constant stirring› is prescribed in order to bring older crystals, as far as possible, into contact with all parts of the slightly supersaturated solution.
Supersaturated solutions of sodium sulphate and sodium thiosulphate, into which crystals of the salts are dropped, show how the crystal starts crystallization.
Thus, in sufficiently supersaturated damp air a cloud is deposited on these charged particles and they are thus rendered visible.
The filtrate is next supersaturated with ammonia, and well shaken with chloroform, which, upon being separated by means of a pipette and evaporated, leaves the alkaloid in an impure state.
The second portion of the solution is supersaturated with nitric acid, and this neutralized by addition of a slight excess of ammonia.
These productive and nourishing waters are supersaturated with all sorts of fatty atoms adapted to the delicate nature of the fish which lazily drink in the nourishment provided for them by the fertile and generous common mother.
In the former case the solutions are unsaturated, in the latter case they are supersaturated with respect to a certain solid phase; in themselves, the solutions are stable, and are neither unsaturated nor supersaturated.
Conversely, above the transition point, the saturated solution of the racemate would be supersaturated with respect to the two tartrates, and transformation into the latter would ensue.
D), the solutions are supersaturated with respect to the heptahydrate; point D is the eutectic point for dodecahydrate and heptahydrate.
The curve EDF, therefore, must lie above the point C, in the region representing solutions supersaturatedwith respect to the single salts (Fig.
From this figure, now, it is seen that a solution saturated with respect to double salt alone (point D), is supersaturated with respect to the component A.
Two of these solutions, however, would be metastable and supersaturated with respect to the decahydrate.
A solution which is saturated with respect to double salt alone will be supersaturated with respect to potassium chloride.
If, now, the solution is cooled down in contact with the solid salts to just below the transition point, it becomes supersaturated with respect to the racemate, and this will be deposited.
Every crystal grows in a supersaturated medium only up to a definite size, which is determined by its chemical-molecular constitution.
When the water slowly evaporates from a supersaturated solution of Glauber-salt, not only does a crystal slowly grow in it, but several young crystals appear on it.
Even the amorphous powder of the salt causes again the formation of new watery crystals when put in a supersaturated solution.
Ostwald) form so obtained being immediately solidified on the introduction of a particle of the solid modification; and supersaturated solutions behave in a similar manner.
