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 ]
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 ...
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).
In aqueous solution, copper(II) exists as [Cu(H 2 O) 6] 2+. This complex exhibits the fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex. Adding aqueous sodium hydroxide causes the precipitation of light blue solid copper(II) hydroxide. A simplified equation is:

Copper sulfate may refer to: Copper(II) sulfate , CuSO 4 , a common, greenish blue compound used as a fungicide and herbicide Copper(I) sulfate , Cu 2 SO 4 , an unstable white solid which is uncommonly used
Chevreul's salt is prepared by treating aqueous copper(II) sulfate with a solution of potassium metabisulfite. The solution changes colour from blue to green immediately. The identity of the green species is unknown. Heating this solution produces a reddish solid precipitate: 3 CuSO 4 + 4 K 2 S 2 O 5 + 3 H 2 O → Cu 3 (SO 3) 2 •2H 2 O + 4 K ...
Copper hydride is an inorganic compound with the chemical formula CuH n where n ~ 0.95. [3] It is a red solid, rarely isolated as a pure composition, that decomposes to the elements. [ 4 ] Copper hydride is mainly produced as a reducing agent in organic synthesis and as a precursor to various catalysts.
