The Principles of Chemistry by Demetri Mendeleev

At 60 degrees, a saturated solution contains 45.7 parts of potassium chloride per 100 parts by weight of water. The amount of salt remaining in solution at 0 degrees is calculated as follows: In 200 grams taken, there will be 137.3 grams of water. Consequently, this amount of water is capable of holding only 40.1 grams of the dissolved salt. And that seems as good a place as any to end this evening's reading from the Principles of Chemistry by Demetri Mendeleev. Once again, I wonder how much better I would have done in chemistry if this had been my textbook because he has a marvelous way of explaining basics. If you'd like to read this seminal
