WebAs long the layer of plastic is not scratch or removed by vigorous cleaning, the copper will be protected and malachite will form on its surface. Method: In this experiment the percentage of copper in basic copper (II) carbonate, CuCO3·Cu (OH)2, will be determined experimentally by the thermal decomposition of the compound. http://webmineral.com/data/Azurite.shtml WebUpon reaction of 1.274 g of copper sulfate with excess zinc metal, 0.392 g copper metal was obtained according to the equation: \[\ce{CuSO4}(aq)+\ce{Zn}(s)\rightarrow \ce{Cu}(s)+\ce{ZnSO4}(aq) \nonumber\] ...
