Notice that, as I permit the solution to flow into the lime-water, the same white powder appears as before; but, now, notice further that, as I continue to add the solution of carbonic dioxide, this white solid redissolves, and we have a beautifully clear solution. It is generally believed that, under these conditions, in presence of a great excess of carbonic, dioxide, the molecule of calcic carbonate combines with additional atoms of carbon, oxygen, and hydrogen, to form the very complex molecule H2CaC2Oc, which is assumed to be soluble in water; but, as this point is one of doubt, I prefer to present the phenomenon to you as simply one of solution, and as illustrating a remarkable point in our chemical philosophy--the fact that the production of a given compound is frequently determined by the circumstance of its insolubility. The calcic carbonate forms, in the first instance, because this compound is insoluble; but, when a proper solvent like the aerated water is present in sufficient excess, no such compound results, or, at least, we have no evidence of its formation. Most of my audience will be more interested, however, in this solution of chalk in soda-water (for such it is), from the fact that it plays a very important part in Nature, and is a common feature of domestic experience. Such a solution as this is what we call hard water, and spring-water is frequently in this condition. Such water is said to kill soap, and is disagreeable when used in washing, because the lime in solution forms with the fatty constituent of the soap an insoluble, sticky mass, which adheres to the hands or cloth.
