About the item:
The copper above was made through copper reduction from pure copper nitrate. The reducing agent was cobalt. To insure purity the reduced copper was reacted in 32% HCl to turn all traces of remaining cobalt to cobalt chloride. Substance was then washed several times in purified water to remove all soluble traces of cobalt chloride.
