An element is found in one part that may not be found in another. Hydrogen shows its line in the spectrum derived from every heavenly body that has been investigated; but not so aluminium or cobalt. Sodium, that is, the salt-producing base, is discovered everywhere, but not nickel or arsenium.
"By all means," said Mr. Furlong. Mr. Fyshe poured out a wineglassful of soda and handed it to the rector to drink. "Now tell me very truthfully," he said, "is there too much carbon in it?" "By no means," said Mr. Furlong. "And quite frankly not too much hydrogen?" "Oh, decidedly not." "And you would not say that the percentage of sodium bicarbonate was too great for the ordinary taste?"
"Not in the sense of containing injurious alkali, like sodium carbonate, the compound which is found in the 'black alkali' lands of the arid regions of the far West; but chemically considered limestone is truly an alkali; and, as such, it has power to neutralze this soil acidity." "Is the acidity harmful to the crops?"
As an example, we may take the determinations of the melting-points of mixtures of potassium and sodium nitrate by M. Maumené. From this diagram we should be led to expect a eutectic mixture, since the curve dips below a horizontal line passing through the melting-point of the more fusible of its constituents. From our curve we should expect a eutectic mixture with about 35 per cent.
Experiments already made so that aluminum, silicon, boron, manganese, magnesium, sodium and potassium can be reduced from their oxides with ease. In fact, there is no oxide that can withstand temperatures attainable in this electrical furnace. Charcoal is changed to graphite. Does this indicate fusion or solution of carbon?
Oxide of magnesium Trace Trace Oxide of potassium Trace Oxide of sodium Trace Carbon dioxide Trace It is produced by some species of the dipterocarpus or shorea which it is impossible to determine. ... It should not be confounded with the other common almaciga from the trees of the genus Agathis.
He threw bright sunshine across a space occupied by vapour of sodium, and perceived with astonishment that the dark Fraunhofer line D, instead of being effaced by flame giving a luminous ray of the same refrangibility, was deepened and thickened by the superposition. He tried the same experiment, substituting for sunbeams light from a Drummond lamp, and with similar result.
Little Borax Lake covers only about thirty acres, and this is now worked. The efflorescing matter is composed of carbonate of soda, chloride of sodium, and biborate of soda. The object of the works is, of course, to separate the borax, and this is accomplished by crystallizing the borax, which, being the least soluble of the salts, is the first to crystallize.
I made the height of it manufacturing Aunt Patty's Silver Soap. I invented the art of making it. I experimented for three years before I got just the right quantity of chloride of sodium solution and caustic potash mixture to curdle properly. And after I had taken some $9,000,000 out of the soap business I made the rest in corn and wheat futures.
From an aqueous solution calcium sulphate is deposited as crystals of gypsum, but when the solution contains an excess of sodium or potassium chloride anhydrite is deposited. This is one of the several methods by which the mineral has been prepared artificially, and is identical with its mode of origin in nature, the mineral having crystallized out in salt basins.
