Copper(II) chloride (CuCl2CuCl_2CuCl2)
Insoluble metal base
Increases reaction rate
Excess CuOCuOCuO remains undissolved
Remove unreacted excess CuOCuOCuO
Increase concentration of salt
Crystals form as solution cools
2HCl+CuO→CuCl2+H2O2HCl + CuO → CuCl_2 + H_2O2HCl+CuO→CuCl2+H2O
Ensures all acid is neutralised
Separate solids from liquids
Filter and dry the crystals
