   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, [8] while its anhydrous form is white. [9]

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 ...
