Make Copper (II) Chloride
Here, I will make Copper (II) Chloride.
First, slowly combine 60mL of water and 60mL of concentrated Hydrochloric Acid in a beaker, then add to a reaction vessel. After that measure out 120 mL of 3% Hydrogen Peroxide and add that in as well. Finally, add in an excess of copper metal and let it react until it stops bubbling. Add the solution to a beaker, and boil down until crystals form. Let the solution cool down, and filter off the crystals. Let the crystals dry, then store however wanted. The overall reaction is Cu + 2HCl + H2O2 ⇒ CuCl2.2H2O.
