Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4. It forms hydrates CuSO 4 · n H 2 O , where n can range from 1 to 7. The pentahydrate ( n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [ 10 ] while its anhydrous form is white. [ 11 ]
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color . Copper also has a range of different organic and inorganic salts , having varying oxidation states ranging from (0,I) to (III).
Specifically, using Benedict's reagent and Fehling's solution the presence of the sugar is signaled by a color change from blue Cu(II) to reddish copper(I) oxide. [4] Schweizer's reagent and related complexes with ethylenediamine and other amines dissolve cellulose. [5] Amino acids such as cystine form very stable chelate complexes with copper(II).
An ionic compound is named by its cation followed by its anion. See polyatomic ion for a list of possible ions. For cations that take on multiple charges, the charge is written using Roman numerals in parentheses immediately following the element name. For example, Cu(NO 3) 2 is copper(II) nitrate, because the charge of two nitrate ions (NO −
Blue vitriol – copper(II) sulfate pentahydrate. Green vitriol – a mineral; iron(II) sulfate heptahydrate. (or ferrous sulfate) Red vitriol - cobalt sulfate. [1] Sweet vitriol – diethyl ether. It could be made by mixing oil of vitriol with spirit of wine and heating it. [2] White vitriol – zinc sulfate, formed by lixiviating roasted zinc ...

A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
In alchemy the symbol for copper was also the symbol for the goddess and planet Venus. Chalcolithic copper mine in Timna Valley, Negev Desert, Israel. In Greece, copper was known by the name chalkos (χαλκός). It was an important resource for the Romans, Greeks and other ancient peoples.
