Σελίδα 52 - ... having drank a Flask of Florence at a Tavern, and thrown the empty Flask upon the Fire, he call'd for a Bason of Water to wash his Hands, and perceiving that the little Wine left in the Flask had filled up the Flask with Steam, he took the Flask by the Neck and plunged the Mouth of it under the Surface of the Water in the Bason, and the Water of the Bason was immediately driven up into the Flask by the Pressure of the Air.
Σελίδα 106 - ... in a solution of sodium hypochlorite. Note the results. Cut the tube containing the deposit so as just to remove the jet, and, inclining it, 0 FIG. 49 apply a gentle heat, as in b. Account for the results and write the equations for all the reactions involved in the experiment. 150. Arsenious oxide. Place a very little arsenious oxide in a test tube and add a few cubic centimeters of a solution of sodium hydroxide, heating the solution gently. Does the oxide dissolve (R) ? What do you infer as...
Σελίδα 71 - ... powdered brimstone in a test tube. Cover the mouth of the tube with the thumb and shake the contents gently until the sulfur is dissolved, adding more carbon disulfide if necessary. Pour the clear solution into a small beaker, cover it loosely with a filter paper, and set it aside in the hood.
Σελίδα 95 - ... of water. What action takes place ? Test the reaction of the water with litmus paper. Holding the test tube in an inverted position (why?), remove it from the water and quickly ignite the gas at the mouth of the tube. How does the flame compare with that of burning ethylene and burning methane ? 6. Collect another test tube full of the gas, quickly pour into it about 1 cc. of bromine water, close the mouth of the tube with the thumb, and shake it vigorously. Is the bromine absorbed by the acetylene...
Σελίδα 103 - Phosphorous acid. Pour into a test tube about 0.5 cc. of phosphorus trichloride (hood) and add a little water, a drop at a time. What gas is evolved (R) ? Finally, add about 5 cc. of water, pour the liquid into an evaporatingdish, and evaporate to a sirupy mass. Dilute this with a little water, transfer the solution to a test tube, and add a few drops of a solution of silver nitrate. Boil the resulting mixture. A black precipitate forms. Explain.
