R. Akermann, of Stockholm, C.G. Saernstrom has conducted a similar series of forty-five experiments, the expense being borne by the Jernkontor. This was exposed to the action of a current of mixed carbon dioxide and monoxide made by heating oxalic acid and concentrated sulphuric acid. It was mixed with carbon dioxide as required, then analyzed, and preserved in gasometers holding 66 liters.
In the selection of the appropriate antidote, a knowledge of pharmacology is required, especially of the physiological antagonism of drugs. Antidotes may act chemically, by forming harmless compounds, as lime in oxalic acid poisoning; physiologically, the drug which is administered neutralizing more or less completely the poison which has been absorbed; physically, as charcoal.
Oxalic acid is an active poison; many persons have fallen victims to its virulence, by having swallowed it in mistake for Epsom salt, which it resembles in appearance. In all probability, this would not prove to be the only vegetable acid capable of acting as a poison. Chalk finely powdered, and diffused in water, is the proper antidote to the poison of oxalic acid. The Plain Truth.
Then he tried, each in turn, some oxalic, cyanic, acetic, phosphoric, chloric, hyperchloric, sulphuric, boracic, silicic, nitric, formic, nitrous nitric, and carbonic acids. Mrs. Peterkin tasted each, and said the flavor was pleasant, but not precisely that of coffee.
"When the concierge went up this morning to take a letter she could get no answer to her ring. She heard someone groaning. The door wasn't locked, and she went in. Blanche was lying on the bed. She'd been frightfully sick. There was a bottle of oxalic acid on the table." Stroeve hid his face in his hands and swayed backwards and forwards, groaning. "Was she conscious?" "Yes.
Nearly every disease originating in the human body is due to or accompanied by the excessive formation of different kinds of acids in the system, the most important of which are uric, carbonic, sulphuric, phosphoric and oxalic acids.
I declared, with reason, that I had drunk too much already, and crept away to my bed, which happily was close at hand. For at least two days after that incident I smelt like a newly-painted lamp-post, but I have always felt grateful to the careless dog of a servant for not having served me up oxalic acid or vitriol in place of the turpentine.
In the sight of Heaven we are all equal, and I'm an eloper. I'm a faithless hound. That's not all, Jingle. They've thrown me out of the business. And that's not all. I bought four packets of oxalic acid. I've put them down where Mabel is bound to see them. There's one on her pillow, one on the clock, one on the piano, and one on the mantelpiece. You see? I'm a murderer.
!Answer!: 20.08 cc. !Answer!: 5.70 cc. A sample of pyrolusite weighing 0.6000 gram is treated with 0.9000 gram of oxalic acid. What is the percentage of MnO , in the sample? !Answer!: 84.47%. A solution contains 50 grams of KHC O .H C O .2H O per liter. In the analysis of an iron ore containing 60% Fe O , a sample weighing 0.5000 gram is taken and the iron is reduced with sulphurous acid.
Prussiate of potash when brought into contact with the perchloride of iron immediately turns the latter blue, but it does not affect the protochloride. A bath is first prepared consisting of ten parts perchloride of iron, five parts oxalic or some other vegetable acid, and one hundred parts water.
