  2. Benedict's reagent - Wikipedia

    en.wikipedia.org/wiki/Benedict's_reagent

    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]

  3. Copper(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Copper(II)_sulfate

    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]

  4. Bordeaux mixture - Wikipedia

    en.wikipedia.org/wiki/Bordeaux_mixture

    Bordeaux mixture (also called Bordo Mix) is a mixture of copper(II) sulphate (CuSO 4) and quicklime (Ca O) used as a fungicide. It is used in vineyards, fruit-farms, vegetable-farms and gardens to prevent infestations of downy mildew, powdery mildew and other fungi. It is sprayed on plants as a preventive treatment; its mode of action is ...

  5. Copper(I) sulfate - Wikipedia

    en.wikipedia.org/wiki/Copper(I)_sulfate

    Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu 2 SO 4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available. [1]

  6. Biuret test - Wikipedia

    en.wikipedia.org/wiki/Biuret_test

    An aqueous sample is treated with an equal volume of 1% strong base (sodium or potassium hydroxide) followed by a few drops of aqueous copper(II) sulfate. If the solution turns purple, it contains protein. 5–160 mg/mL can be determined. Peptides with the correct length of at least 3 amino acids are necessary for a significant, measurable ...

  7. Fehling's solution - Wikipedia

    en.wikipedia.org/wiki/Fehling's_solution

    Fehling's solution is prepared by combining two separate solutions: Fehling's A, which is a deep blue aqueous solution of copper(II) sulfate, and Fehling's B, which is a colorless solution of aqueous potassium sodium tartrate (also known as Rochelle salt) made strongly alkaline with sodium hydroxide. These two solutions, stable separately, are ...

  8. Copper toxicity - Wikipedia

    en.wikipedia.org/wiki/Copper_toxicity

    Copper toxicity (or Copperiedus) is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions.

  9. Talk:Copper (II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Talk:Copper(II)_sulfate

    "It can also be prepared by electrolysis of magnesium sulfate [Epsom salts] solution at moderate voltage with a copper anode: this reaction produces hydrogen, copper sulfate solution, and copper hydroxide precipitate." what happens to the magnesium? MgSO4(aq) + Cu(S) --dc--> h2(g) + Mg(OH)2(s) + CuSO4(aq) would make more sense.
