Copper ions release more readily under acidic conditions and copper pesticides, except copper sulfate pentahydrate, should not be used with acid forming products. [10] Copper fungicides can be highly effective if applied prophylactically and with complete coverage of all plant foliar surfaces, including the undersides of leaves where the ...
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 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]
Chalcanthite is a pentahydrate and the most common member of a group of similar hydrated sulfates, the chalcanthite group. These other sulfates are identical in chemical composition to chalcanthite, with the exception of replacement of the copper ion by either manganese as jokokuite , iron as melanterite , or magnesium as pentahydrite .
Compared to copper sulfate, the alpha crystal form of basic copper chloride provides many benefits including improved feed stability, less oxidative destruction of vitamins and other essential feed ingredients; superior blending in feed mixtures, and reduced handing costs.
Burgundy mixture, named after the French district where it was first used to treat grapes and vines, [1] is a mixture of copper sulfate and sodium carbonate. This mixture, which can have an overall copper concentration within the range of 1% through 20%, [ 2 ] is used as a fungicidal spray for trees and small fruits.
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 ...
Cu 2 SO 4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide: [4] Cu 2 O + (CH 3 O) 2 SO 2 → Cu 2 SO 4 + (CH 3) 2 O. The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentahydrate upon contact with water. [4]
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 ...
