  2. 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]

    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]

    en.wikipedia.org/wiki/Copper_compounds

    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:

  7. List of copper salts - Wikipedia

    en.wikipedia.org/wiki/List_of_copper_salts

    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).

  8. Bordeaux mixture - Wikipedia

    en.wikipedia.org/wiki/Bordeaux_mixture

    Bordeaux mixture has been found to be harmful to fish, livestock and—due to potential buildup of copper in the soil—earthworms. [1] [2] The chemical was in use as a blight preventive in the potato country of northern Maine by 1921. [5] It started to be used by the United Fruit Company throughout Latin America around 1922.

  9. Chalcanthite - Wikipedia

    en.wikipedia.org/wiki/Chalcanthite

    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.
