Note 25 — MINERALS.
Reading edition
Phosphoric Acid is produced by a combination of oxygen (21) with phosphorus (47); and, when obtained in a state of purity, is not a fluid, but a white and flaky substance. This acid, when combined with mineral productions, forms those salts which have the name of phosphats. It is very soluble in water; and, in dissolving, makes a hissing noise, similar to that produced by plunging hot iron into water.
