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]
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
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 ...
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 ...
The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. [2] So low is the toxicity of copper that copper(II) sulfate is a routine reagent in undergraduate chemistry laboratories.
It is composed of a mixture of two solutions. Part A is 0.5 g of copper (II) sulfate in 100 ml of distilled water. Part B consists of 5% pyridine (v/v) in chloroform. [1] [2] One drop of each is added to the substance to be tested and any change in colour is observed. The test turns phenobarbital, pentobarbital and secobarbital light purple ...
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 ...
Instead of copying all the details across, I was hoping to gradually move it over. Make Copper(II) sulfate about the anhydrous and aqeuous forms, only summarizing the hydrated forms. Make Copper(II) sulfate pentahydrate about the more systems, and behaviour of the hydrate. Plasmic Physics 00:03, 4 October 2011 (UTC)
