1. Copperasnoun

   A name given to three sorts of vitriol; the green, the bluish green, and the white, which are produced in the mines of Germany, Hungary, and other countries. But what is commonly sold here for copperas, is an artificial vitriol, made of a kind of stones found on the seashore in Essex, Hampshire, and so westward, ordinarily called gold stones from their colour. They abound with iron, and are exposed to the weather in beds above ground, and receive the rains and dews, which in time breaks and dissolves the stones: the liquor that runs off is pumped into boilers, in which is first put old iron, which, in boiling, dissolves. When the boiling is finished, the liquor is drawn off into coolers, where it shoots into crystals of a fine green colour. This factitious copperas, in many respects, perfectly agrees with the native green vitriol of Germany; and is used in dying hats and cloths black, and in making ink. Ephraim Chambers Hill.

   Etymology: kopperoose, Dut. couperouse, Fr. supposed to be found in copper mines only.

   It may be questioned, whether, in this operation, the iron or copperas be transmuted, from the cognation of copperas with copper, and the iron remaining after conversion. Brown.

1. copperas

   Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO4·xH2O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known. The hydrated form is used medically to treat iron deficiency, and also for industrial applications. Known since ancient times as copperas and as green vitriol (vitriol is an archaic name for sulfate), the blue-green heptahydrate (hydrate with 7 molecules of water) is the most common form of this material. All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas.It is on the World Health Organization's List of Essential Medicines. In 2020, it was the 116th most commonly prescribed medication in the United States, with more than 5 million prescriptions.
