QUOTE(azwan92 @ Jan 12 2010, 01:13 AM) excuse me sir, i have just learn in chemistry in school that copper oxide is black colour. google it also can. Copper oxidizes slowly in air, corroding to produce a brown or green patina. At higher temperatures the process is much faster and produces mainly black copper oxide.http://jchemed.chem.wisc.edu/JCESoft/CCA/C...DOXCU/PAGE1.HTM |
