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]

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]
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]
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. The mixture was nicknamed perico, or "parakeet", because it would turn workers completely blue. Many workers would get sick or die of copper poisoning. [6]
This is due to the presence of the chemical compound coumarin in the bean. Coumarin has been linked to liver failure, but only at unreasonably high concentrations. Related: ...
They are very reactive towards oxygen to form copper(I) oxide and have many uses in chemistry. They are synthesized by treating copper(I) compounds with Grignard reagents , terminal alkynes or organolithium reagents ; [ 12 ] in particular, the last reaction described produces a Gilman reagent .
