During this experiment, we were trying to see whether copper, after a chain of chemical reactions, will revert back to its elemental form procedure: first, i added nitric acid with copper in a beaker, which turned into a copper nitrate, a blue-green solution afterwards, i added sodium hydroxide.
This simple lab demonstrates chemical transformations in and the conservation of copper. We did an lab in class where we added naoh to copper in the first reaction which iscu(no3)2 + 2naoh - cu(oh)2 + 2nano3 how could you tell that not all the copper has precipitated because you did not add enough naoh.
