The etching solution eventually becomes saturated with copper (II) oxide, which starts precipitating out of the solution as a blue-green solid. It takes a while to get there, though; depending on ...

If we take a look at the specifications which Fujikura lists for CCA (also called CAW), we can see that while CCA isn’t as good as solid copper wire, it is significantly better than solid ...

For example: copper carbonate decomposes on heating to make solid copper oxide, which stays in the boiling tube, and carbon dioxide gas, which escapes magnesium reacts with oxygen, gained from the ...
