If you decided to grow a very large crystal and to do it in a beaker, prepare in advance 60-70 grams of copper sulfate. Fully dissolve the copper sulphate in hot water. Thoroughly mix the solution until there are no crystallites remaining. Use a piece of copper wire, thread or a splinter as the "support" of the crystal. Now please be patient!

purifying copper by electrolysis. The copper(II) ions are removed again from the organic solvent by reaction with fresh sulphuric acid, producing a much more concentrated copper(II) sulphate solution than before Electrolysis of the new solution Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below).

In this case I have chosen copper sulphate solution to electrolyse. In the experiment when the solution is being electrolysed it starts to decompose and at cathode there is copper formed and oxygen at the anode. This is caused by electricity from the power supply, which has caused a chemical change.

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

In contrast, crystal fragments of the coarse-grained trihydrate sample were weighed out and used for calorimetry experiments without grinding. Directly after the weighing, the samples were dropped through a SiO 2 glass tube into the solvent, and the heat produced or consumed during the dissolution was measured.

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.

Add denatured alcohol to the solution until all the [Cu(NH3)4]SO4 precipitates. Filter the precipitate and add a little more alcohol to make it as free of water as possible. Water will cause the formation of copper(II) oxide when this is heated. Heat the precipitate until all ammonia has evaporated, leaving the white, anhydrous copper sulfate.
