I know! It has dissolved. M. Quite right. Taste the water so as to convince yourself. P. Horrid, like soap! M. You have discovered one reaction of the compound which is formed. But we will speak of that later. Let us pay attention to hydrogen at present. What does it look like? P. Like air. M. Yes, hydrogen is a colourless gas. Now I take the tube out of the water, closing the mouth with my 134 CONVERSATIONS ON CHEMISTRY. Thumb, and take away my thumb when I bring it near a flame. What do you s...ee? P. The hydrogen appears to burn; but the flame is very pale. M. Quite right. Hydrogen is a combustible gas. But in order to learn more about its properties we should have to put sodium again under the mouth of the tube, and that would be tiresome. I will rather show you another method of making hydrogen, by which it is much easier to produce large quantities. For this pur- pose we take other compounds of hydrogen which give it up more readily than water does. Such a compound is hydrochloric acid; as its name implies it consists of hydrogen and chlorine.
