By combining with water these oxides all form acids the sulphurous (H2 S Os) and the sulphuric (H2 S 04) being very useful substances. The former is used for bleaching straw and woolen goods; the latter, in immense quantities, for the manufacture of chemicals. III.--THE TEIVALENT H0N-METAL8, OK KITKOGEH GKOTJP (28.) Phosphorus, in small proportions, is found in some minerals, and is a most important element in organic bodies.-It is obtained from bones. It is a waxy-looking solid, shining in the dark, and having a strong attraction for oxygen. 1. Phosphorus in nature.--Compounds containing phosphorus are quite common in soils and rocks. Plants receive them from the soil, while animals, living upon vegetable food, take these compounds from the plant. It is found in wheat and other grains, and in the brain and secretions of animals: so that while not very abundant, it is a widely distributed and very important element. Its most common compounds are the phosphates, and of these the most abundant is the calcic phosphate. This compound of phosphorus occurs in bones, and from these the element is obtained. 2. Its physical properties.--Phosphorus is a solid element, having a pale yellow color, rather soft and wax-like at common temperature, but brittle at 32 F. In a dark room its clean surface shines with a feeble, pearl-white light. Its vapor also is beautifully phosphorescent. To show this, put a few small fragments of the solid into a flask of water and boil it. The mixed vapors of water and phosphorus escape, and, in a dark room, look like livid flames, while at the same time globules of melted phosphorus, on the surfaces of the water and the ...
