A Crystal Lab - ia

Copper sulfate pentahydrate will grow beautiful blue rhombic crystals. The quality of the crystals greatly depends on the quality of the copper sulfate compound used. If you have crystalline reagent grade cupric sulfate, you will get first-rate crystals. Try to avoid using powered copper sulfate, as it does not produce very good results.

Investigation of process parameters in electroless copper ...

particles for the plating come from copper sulfate and formaldehyde (HCHO) acts as the reducing agent. Caustic soda (NaOH) controls the alkalinity of the solution (pH), compounds such as sodium-potassium tartrate keep the copper soluble in the solution and stabilizers, present in small amounts of 1–20 ppm, stabilizes the solution. It is the

Making Copper Powder From Aluminum Foil | ChemTalk

Copper itself is a reddish-brown metal, but aqueous copper sulfate solution is a beautiful bright blue color. This is due to the coordination complex the Cu 2+ ion forms with water—copper sulfate absorbs photons of light in the red region of the visible spectrum, thus transmitting blue light, making the solution appear blue.

Science made alive: Chemistry/Experiments

Formation of black copper(II) isothiocyanate. Totally different results are obtained when a concentrated solution of copper(II) sulfate is added to a fairly concentrated solution of potassium thiocyanate, with copper(II) ion in excess. When this is done, a black precipitate is formed at once, which remains black on standing.
