To quickly assess the difficulty of the text, read a short excerpt:
Experiment 47. — Analysis of Air.
By Prof. LeRoy C. Cooley, Ph.D. t in "A Guide to Elementary Chemistry for Beginner 8. " We set out now to find how many cubic centimetres of nitrogen and how many of oxygen and carbon dioxide there are in 100 c. c.
of air.
To do this we will imprison a vesselful of air, and then run into it a liquid which will absorb both the oxygen and the carbon dioxide com- pletely, and leave the nitrogen. We can then measure the nitrogen which is left, and we can find out h...ow much there was of the other two by measuring the liquid which had gone into the tube to take their place.
Our Apparatus. — I take a test-tube, t (Fig. 11), to hold the air. A six-inch tube, | inch in diameter, will do ; an eight- inch tube of the same diameter is better. The rubber stopper, c, is so large that its small end will enter the tube only about a half-inch. It has two holes ; to close one I have a solid rod of glass, 8 ; for, the other, a glass tube reaching just a t |a, very little below the cork, as shown.
