Solution of caustic potash is then added to the ethereal solution, forming bromide of potassium and bromate of potash. This solution is evaporated to dryness, and the salts being collected are heated in a glass retort with sulphuric acid and a little oxide of manganese. The bromine is distilled, and is condensed in a cooled receiver, into a red liquid. Properties.
Concentrated sulphuric acid forms an insoluble downy white precipitate, and the concentrated vegetable acids, with the exception of tannic acid, do not determine any precipitate. Cerealine coagulated by an acid redissolves in an excess of the same acid, but it has become dead and has no more action on the starch.
Before using, it is passed over phosphorus and chloride of calcium, and through sulphuric acid. The porcelain tube and boat were heated to from 300 deg. to 600 deg. It was found that the larger the quantity of dioxide the higher the degree of oxidation, and the larger the proportion of monoxide the lower the degree of oxidation.
Pa seems to want to encourage me, and is willing to take anything that I ask him to, He had a sore throat and wanted something for it, and the boss drugger told me to put some tannin and chlorate of potash in a mortar, and grind it, and I let Pa pound it with the mortar, and while he was pounding I dropped in a couple of drops of sulphuric acid, and it exploded and blowed Pa's hat clear across the store, and Pa was whiter than a sheet.
Long told the young men that the inhalation of sulphuric ether would have the same effect. He had become acquainted with this property of ether while studying medicine in Philadelphia. The young men and their friends were so well pleased with the effects of ether inhalation, that "ether parties" became fashionable in that section, as well as in other parts of the State. At these ether parties, Dr.
The passage of air through red-hot glass tubes, or through strong sulphuric acid, does not alter the proportion of its oxygen, while it must needs arrest, or destroy, any organic matter which may be contained in the air.

A quantity of the water, equal in bulk to one thousand grains of distilled water, was operated on for each of the following ingredients: Chlorine 0.66 Carbonic acid 0.16 Sulphuric acid 0.03 Soda and sodium 0.97 Magnesia 0.09 Lime 0.07 Potash traces Organic matter ,, Manganese ,, 1.98
Strychnine has a characteristic, very bitter taste; it imparts this taste to even very dilute solutions; it is unaffected by sulphuric acid, but gives a purple-blue colour, changing to crimson and light red, when the edge of this solution is touched with dioxide of manganese, potassium bichromate, ferricyanide of potassium, or permanganate of potassium.
Caustic alkalies form with it a solution even in the cold, from which the mineral acids precipitate it unchanged. It contains much azote: it dissolves in, and decomposes, sulphuric acid: it easily kindles at the flame of a candle: it has been found to succeed, as a pigment, in some respects better than China ink."
