There, I'm glad I've got it out of my system. I've thought about it a good deal since your man was here to see me." "What do you suspect was the cause of that sweetish odour?" asked Kennedy. The doctor hesitated. "Mind, it is only a suspicion. Cyanide of potassium or cyanogen gas; either would give such an odour." "Your treatment would have been just the same had you been certain?"
"No, not a pound of farm manure has been used on that plot for more than sixty years; and, furthermore, the two plots were very much alike at the beginning; but, to the high-yielding plot, nitrogen, phosphorus, potassium, magnesium, calcium, and sulfur have all been applied in suitable compounds every year." "That is to say," observed Mr.
We see but little of the lady in the 251 pages of this "Fifth Avenue Story"; her character is exposed to us through the experiences of her poor fool husband, who colloquially would be called a simp, by denizens of the Low World a boob. He redeems himself to some extent by sending Madam Sapphira a belated bouquet of cyanide of potassium.
A solution of cyanide of potassium is now added to this precipitate until it is dissolved, during which process the solution becomes warm by the chemical re-action which takes place. The solution is filtered, and allowed to repose all night.
Thus, while potassium melts at 62.5° C., and sodium at about 98°, an alloy of these metals is fluid at ordinary temperatures, and fusible metal melts below the temperature of boiling water, or more than 110° lower than the melting-point of tin, the most fusible of the three metals which enter into the composition of this alloy.
According to this method a stock solution of hypochlorite of lime was added to the water, the amount necessary for any given water being determined by a solution of potassium iodide and starch. This was particularly useful in the trenches where it was possible to accurately sterilize a pail or a barrel of water if necessary.
If we retain the straw on the farm and sell only the grain, the supply of potassium in the surface soil of Poorland Farm is sufficient to meet the needs of a fifty bushel crop of wheat per acre every year for nineteen hundred and twenty years, or longer than the time that has passed since the Master walked among men on the earth; whereas, the total phosphorus content of the same soil is sufficient for only seventy such crops, or for as long as the full life of one man.
"I say, if I am permitted to separate Miss Russell and the Thorntons from about three hundred acres of their land, I shall certainly wish to know its total content of phosphorus, potassium, magnesium, and calcium, before I make any purchase; and, if you will remember the pot cultures and the peaty swamp land, I think you'd agree with me.
Kathleen straightened up, and for the first time stared full at the spy. "The syringe was filled with a solution of cyanide of potassium," continued Henry. "Adjusting the needle, Mrs. Whitney entered the elevator, and before Spencer could move, thrust it into his neck. Spencer gave one convulsive start, attempted to get up, and his heavy body lurched full against her.
Potassium hydroxide which has been exposed to the air is found on analysis to contain 7.62% water, 2.38% K CO . and 90% KOH. What weight of residue will be obtained if one gram of this sample is added to 46 cc. of normal hydrochloric acid and the resulting solution, after exact neutralization with 1.070 N potassium hydroxide solution, is evaporated to dryness? !Answer!: 3.47 grams.
